This page archives significant decisions by the Unicode Technical Committee not to approve certain proposed characters.
Notices of non-approval decisions are numbered for reference, and are listed roughly in reverse chronological order, so that more recent decisions are at the top of the list. The reference number for each notice consists of the year of the original decision, followed by a dash and another digit to indicate sequence order. The date shown at the right of each notice is the posting date for that notice in this archive. Posting dates for a notice may occasionally be updated, whenever the UTC revisits a decision of non-approval and updates the decision in some way. Significant dates related to the actual UTC decision(s) involving a non-approval are listed in the disposition section of each notice.
Note that the UTC routinely declines to approve various character proposals at a particular meeting. In most instances such decisions are simply part of the ongoing process of feedback, revision, and review of exploratory or otherwise incomplete proposals. Such ongoing proposal review does not constitute formal non-approval, and is not tracked on this page.
Occasionally, however, the UTC makes a formal decision to reject a character proposal, for a variety of architectural reasons, or because of other serious defects in the proposal. Such formal decisions result in a notice of non-approval posted on this page, and signal the intent of the UTC not to pursue further work on that proposal. In some instances such a formal decision is also designated by the UTC as constituting a precedent (see Section 10.6.2, "Precedents" in the UTC Procedures); any precedent would require a special majority in the UTC to be reconsidered for a change of decision at a later time. Any notices of non-approval which also constitute UTC precedents are explicitly identified as such in this archive.

| 2008-2 | TELUGU SIGN ARDHAVISARGA | 2008-May-14 |
| Proposal to encode the Vedic ardhavisarga sign as a Telugu script character. L2/06-250. | ||
| Disposition: The originally approved U+0C71 TELUGU SIGN ARDHAVISARGA (2006-Aug-11) was reproposed as a generic Vedic sign. On 2008-May-14, the UTC superseded its earlier approval, and instead approved the generic Vedic sign as U+1CF2 VEDIC SIGN ARDHAVISARGA. References to UTC Minutes: [115-C6] | ||
| 2008-1 | AVESTAN SEPARATION POINT | 2008-Feb-08 |
| Proposal to encode a middle dot as a separation point for Avestan. L2/07-006. | ||
| Disposition: 2008-Feb-08, rejected by the UTC as a duplicate of U+2E31 WORD SEPARATOR MIDDLE DOT. This character had progressed to ballot for Amd 5 to ISO/IEC 10646:2003 (as U+10B38), but was removed from that ballot by disposition of comments, 2008-Apr-25. References to UTC Minutes: [114-A76] | ||
| 2006-1 | MALAYALAM CONSONANT SIGN CILLU | 2006-Nov-08 |
| Proposal to encode a separate cillu sign for use as a diacritic for other Malayalam letters. L2/06-261. | ||
| Disposition: 2006-Nov-08, rejected by the UTC on architectural grounds, as inconsistent with the decision to encode atomic chillu characters for Malayalam. References to UTC Minutes: [109-A74] | ||
| 2004-5 | Capital Double S | 2007-May-18 |
| Proposal to encode a Capital Double S for German. L2/04-395. | ||
| Disposition: 2004-Nov-18, rejected by the UTC as a typographical issue, inappropriate for encoding as a separate character. Rejected also on the grounds that it would cause casing implementation issues for legacy German data. Decision later revisited 2006-May-18, on the basis of a revised proposal, L2/07-108. Now standardized as U+1E9E LATIN CAPITAL LETTER SHARP S in Unicode 5.1. References to UTC Minutes: [101-C22], [101-A74] | ||
| 2004-4 | MODIFIER LETTER STRAIGHT APOSTROPHE | 2006-Nov-10 |
| Proposal to encode an unambiguously straight form of the modifier letter apostrophe, for use in Latin script orthographies. L2/04-372. | ||
| Disposition: 2004-Nov-18, rejected by the UTC as not distinct from existing encoded characters for modifier letter apostrophes. Decision later overturned 2006-Nov-10, on the basis of a revised proposal, L2/06-259, to encode a casing pair of letters. These were standardized as U+A78B LATIN CAPITAL LETTER SALTILLO and U+A78C LATIN SMALL LETTER SALTILLO in Unicode 5.1. References to UTC Minutes: [101-A87] | ||
| 2004-3 | Combining Umlaut | 2004-June-18 |
| Proposal to encode a combining umlaut character, distinct from U+0308 COMBINING DIAERESIS. L2/04-210. | ||
| Disposition: 2004-June-18, rejected by the UTC as an inappropriate disunification of the existing character. Functional disunification of combining marks which otherwise appear identical in appearance is inappropriate, and other mechanisms to maintain this functional distinction in text are available. Proposal was submitted to WG2, 2004-June 21, but never progressed. References to UTC Minutes: [99-C35], [99-M6] | ||
| 2004-2 | Roman Canopy Character | 2004-June-18 |
| Proposal to encode a character to represent the "canopy" mark over Roman numerals in classical Latin text. L2/04-137. | ||
| Disposition: 2004-June-18, rejected by the UTC as inappropriate for encoding as a character. This kind of textual convention should be represented by markup, instead. Proposal was submitted to WG2, 2004-June 21, but never progressed. References to UTC Minutes: [99-A46] | ||
|
|
||
| 2004-1 | Ideographic Square Symbols | 2004-June-18 |
| Proposal to encode two square symbols for use with ideographs: IDEOGRAPHIC WHITE SQUARE and IDEOGRAPHIC BLACK SQUARE. L2/04-029. | ||
| Disposition: 2004-June-18, rejected by the UTC as duplicates of the existing U+25A1 WHITE SQUARE and U+25A0 BLACK SQUARE. Proposal was submitted to WG2, 2004-June-21, but never progressed. References to UTC Minutes: [99-A53] | ||
| 2001-3 | Klingon Script | 2001-May-21 |
| Proposal to encode the Klingon script. L2/97-273, L2/01-212. | ||
| Disposition: 2001-May-21, rejected by the UTC as inappropriate for encoding, for multiple reasons stated in L2/01-212. (Lack of evidence of usage in published literature, lack of organized community interest in its standardization, no resolution of potential trademark and copyright issues, question about its status as a cipher rather than a script, and so on.) References to UTC Minutes: [87-M3], [87-A15] | ||

|
||
| 2001-2 | KHMER SIGN LAAK | 2001-Jan-31 |
| Proposal to encode one sign for the Khmer script, KHMER SIGN LAAK, proposed for U+17DD. | ||
| Disposition: 2001-Jan-31, rejected by the UTC as being just a glyph variant of the existing encoded character U+17D8 KHMER SIGN BEYYAL. The preferred representation of this sign (and its alternates) is by spelling it out explicitly. The proposal was submitted to WG2, but ceased progression on 2000-Sep-25 at ISO Stage 2. References to UTC Minutes: [86-M17], [86-A35] | ||
| 2001-1 | GEORGIAN LETTER U-BRJGU | 2001-Jan-31 |
| Proposal to encode one precomposed Georgian letter. | ||
| Disposition: 2001-Jan-31, rejected by the UTC as a precomposed letter already represented by the sequence <U+10E3, U+0302>. References to UTC Minutes: [86-M22], [86-A52] | ||
|
|
||
| 2000-1 | Ligature Control Characters | 2000-Feb-03 |
| Proposal to encode two ligature control characters, ZERO WIDTH LIGATOR and ZERO WIDTH NONLIGATOR. L2/99-379, L2/00-012, L2/00-025, L2/00-031. | ||
| Disposition: 2000-Feb-03, rejected by the UTC on architectural grounds. The UTC assessment was that no forced control of ligation was feasible, and instead decided to fully document the use of the existing ZWJ and ZWNJ with regard to ligature formation. References to UTC Minutes: [82-M17], [82-M18] | ||
| 1998-1 | Ecological Symbols | 1998-Feb-26 |
| Proposal to encode two symbols related to recycling: RECYCLE SIGN and DER GRUENE PUNKT. L2/98-025. | ||
| Disposition: 1998-Feb-26, rejected by the UTC because of the status of DER GRUENE PUNKT as a trademarked logo. The other symbol was later accepted and standardized as U+2672 UNIVERSAL RECYCLING SYMBOL in Unicode 3.2. | ||
| 1997-3 | MODIFIER LETTER MIDDLE DOT | 1997-Dec-05 |
| Proposal to encode a middle dot character to function as a modifier letter. | ||
| Disposition: 1997-Dec-05, withdrawn by author. | ||
| 1997-2 | Mid-level Hamzah | 1997-Jul-22 |
| Proposal to encode a mid-level hamzah character for the Arabic script. | ||
| Disposition: 1997-Jul-22, withdrawn by author. | ||
| 1997-1 | Phaistos Disc | 2006-May-19 |
| Proposal to encode 45 characters for the Phaistos Disc "script". L2/97-106. | ||
| Disposition: 1997-May-29, proposal not accepted by the UTC, in part because of questions about the identity of the characters in question as a script. A revised proposal for encoding 46 characters as pictographic symbols without a specific claim of them being letters of a script in the Unicode sense was accepted by the UTC on 2006-May-19 and was standardized in Unicode 5.1. | ||
| 1996-4 | Arabic Presentation Forms for Uighur | 1996-Dec-06 |
| Proposal to encode a large number of Arabic presentation forms for Arabic letters used in the Uighur, Kazakh, and Kirghiz languages. | ||
| Disposition: 1996-Dec-06, rejected by the UTC on architectural grounds. Encoding of positional variant glyphs for Arabic letters as characters is not required for correct rendering support, and cannot be justified by analogy to earlier sets of Arabic presentations forms encoded as compatibility characters. | ||
| 1996-3 | Yoruba Precomposed Latin Letters | 1996-Sep-07 |
| Proposal to encode 14 precomposed Latin letters, for use in representing the Yoruba language. | ||
| Disposition: 1996-Sep-07, rejected by the UTC as precomposed letters already represented by encoded letters plus combining marks. | ||
| 1996-2 | Armenian Punctuation Characters | 1997-Jul-04 |
| Proposal to encode 15 Armenian script-specific punctuation characters. | ||
| Disposition: 1996-Mar-06, rejected by the UTC on the grounds that most of the proposed characters were unnecessary disunifications of already-encoded general punctuation characters. 1997-Jul-04, proposal stopped progress in WG2 at Stage 2. One character was accepted and later standardized as U+058A ARMENIAN HYPHEN. | ||
| 1996-1 | SOFT SPACE | [1996] |
| Proposal to encode a conditional space character. | ||
| Disposition: Rejected by the UTC on architectural grounds. | ||
