Script Edge Cases

Mark Davis, 2009-01-30 (R2)
Live doc: https://docs.google.com/Doc?id=dfqr8rd5_371fzqg88g8
In most cases, the assignment of scripts works quite well. There are, however, some edge cases that people may stumble over (as I did). I suggest that we document such cases in a new section of TR24.

In particular, the characters that are associated with multiple scripts may need to be grouped with each of the scripts in particular applications. (See, for example, the mockup at http://macchiato.com/picker/MyApplication.html.)

The following is a suggested list of characters for such a section, with guesses as to how to document them. (I make give some suggested property changes, but even if we don't make any, I think it is important to document the situation in one place.) The characters are all listed here for discussion - for the actual text they could be more compactly represented by ranges.

The tentative values I have are marked with @..., just to make it easy to extract the information in tools. As I said before,

Note: if a PDF is in the doc registry, an HTML version should be there also, so that the links work. In the notes below, "explicit script" means a script other than Common or Inherited.

@Devanagari

Am guessing these are Devanagari script.

@Devanagari, Bengali, Gurmukhi, Gujarati, Oriya, Tamil, Telugu, Kannada, Malayalam

The annotations say "scripts of India" for the first set, and "The Vedic signs for jihvamuliya and upadhmaniya were encoded in the Kannada block, but are intended for general Vedic use with all scripts", but the former probably doesn't include Arabic (Urdu), and the latter probably also means "with all Indic scripts". Am guessing that "Indic script" means the above.

Don't know exactly what "Philippine scripts" is supposed to be; am guessing the above.

Math Symbols with specific scripts

The following are the only Sm (Math_Symbol) with explicit scripts (856 GC=Sm characters don't, and 1,027 Math=true characters don't) or are Letterlike-symbols. The Arabic ones seem ok (if they are not used in Syriac, etc). Should the Greek one be Common script?

@Common

Greek And Coptic - Variant letterforms and symbols

U+03F6 ( ϶ ) GREEK REVERSED LUNATE EPSILON SYMBOL

@No-Change

Arabic - Radix symbols

U+0606 ( ؆ ) ARABIC-INDIC CUBE ROOT
U+0607 ( ؇ ) ARABIC-INDIC FOURTH ROOT

Arabic - Letterlike symbol

U+0608 ( ‎؈‎ ) ARABIC RAY

Letterlike Symbols - Double-struck large operator

U+2140 ( ⅀ ) DOUBLE-STRUCK N-ARY SUMMATION

Letterlike Symbols - Additional letterlike symbols

U+2141 ( ⅁ ) TURNED SANS-SERIF CAPITAL G
U+2142 ( ⅂ ) TURNED SANS-SERIF CAPITAL L
U+2143 ( ⅃ ) REVERSED SANS-SERIF CAPITAL L
U+2144 ( ⅄ ) TURNED SANS-SERIF CAPITAL Y
U+214B ( ⅋ ) TURNED AMPERSAND


Characters whose canonical equivalents don't match in script

[Ed note: see also actions 110-A092, and 113-A036, and L2/07-071 ]

The following characters are Script=Greek, but their canonical equivalents are Script=Common. These are the only such characters that change from an explicit script to Common.

Greek Extended - Precomposed polytonic Greek

U+1FC1 ( ῁ ) GREEK DIALYTIKA AND PERISPOMENI
U+1FED ( ῭ ) GREEK DIALYTIKA AND VARIA
U+1FEE ( ΅ ) GREEK DIALYTIKA AND OXIA
U+1FEF ( ` ) GREEK VARIA
U+1FFD ( ´ ) GREEK OXIA

This is not an issue for the other Modifier Symbols (Sk) in Greek blocks:

Greek And Coptic - Numeral signs

U+0375 ( ͵ ) GREEK LOWER NUMERAL SIGN // the only one without a compat decomp.

Greek And Coptic - Spacing accent marks

U+0384 ( ΄ ) GREEK TONOS
U+0385 ( ΅ ) GREEK DIALYTIKA TONOS

Greek Extended - Precomposed polytonic Greek

U+1FBD ( ᾽ ) GREEK KORONIS
U+1FBF ( ᾿ ) GREEK PSILI
U+1FC0 ( ῀ ) GREEK PERISPOMENI
U+1FCD ( ῍ ) GREEK PSILI AND VARIA
U+1FCE ( ῎ ) GREEK PSILI AND OXIA
U+1FCF ( ῏ ) GREEK PSILI AND PERISPOMENI
U+1FDD ( ῝ ) GREEK DASIA AND VARIA
U+1FDE ( ῞ ) GREEK DASIA AND OXIA
U+1FDF ( ῟ ) GREEK DASIA AND PERISPOMENI
U+1FFE ( ῾ ) GREEK DASIA

Or the other Modifier Letters (Lm) in Greek blocks:

Greek And Coptic - Numeral signs

U+0374 ( ʹ ) GREEK NUMERAL SIGN

Greek And Coptic - Iota subscript

U+037A ( ͺ ) GREEK YPOGEGRAMMENI

While not having to do with Script, I ran across the following also:

Mc (Combining Marks) without script

These would probably be better as Sk (Modifier_Symbol). We should at least document them as the only cases of Mc that are not letter-like.

Math Symbols not marked with Sm

While Letter in form, these all should behave like Sm; they don't want to case fold, or be treated as parts of words.

The Western numbers are understandable -- the uncircled values are gc=Number, but the uncircled Han characters are not.

Similarly, all parenthesized alphanums are So

So should these be treated as So?
