2. Rationale:

2.1. Lithuanian Letters

2.1.1. Main alphabet

Lithuanian by its grammatical structure is one of the most ancient languages of living Indo-European languages. It is spoken approximately by 5 millions people and is delivered at many Universities all over the world for linguistic studies.

The main Lithuanian alphabet consists at the Latin alphabet (excluding Q, q, W, w, X, x) with extra 18 letters with diacritics (9 capital and 9 small):

These letters are included in 8-bit single-byte coded character sets (ISO/IEC 8859-13, MS CP 1257, IBM CP 775, etc.). Thus there are no problems to use them.

2.1.2. Extended alphabet (with accented letters)

Lithuanian has a free word stress: stress may fall on every syllable of the word. it performs at least two functions. Its constitutive function manifests itself in distinguishing word from a combination of words, cf.:

The second function of word stress is the distinctive function, which distinguishes otherwise identical words by the place where the stress falls, e.g.:

For the word stressing (or accenting) there are three accent marks (or diacritical marks in ISO terms): grave accent, acute accent and tilde. The position of the stress depends on the stress pattern (or accentual paradigm) of the word and its morphological structure (see examples above).

Word stress is expressed by the means of accented letters.

There are 68 accented letters in the Lithuanian language:

The accented letters together with main letters comprise the extended alphabet.

Usage of accented letters goes back to the first Lithuanian writings. The first Lithuanian books were accented, e.g. "Kathechismas" (1595) and "Postilla catholicka" (1599). At present, the publishing practice all dictionaries, special vocabularies and encycklopaediae are accented. Accented letters are used in textbooks for schools, reference books, linguistic texts, and in publication of laws.

In common press (newspapers, fiction, etc.) only the letters of the main Lithuanian alphabet are used. Accented letters are used only in those words where it has a distinctive function.

2.2. 8-bit single-byte coding (National standard code tables)

There are three national code tables in Lithuania for encoding extended alphabet (usually we say "for encoding accented letters"). The basic Lithuanian code table is for UNIX environment (the second half of this table is shown in fig. 1). It defines the basic character repertoire including accented letters. This code table is conformant with ISO/IEC 8859-13, i. e. the codes of all Lithuanian main letters in both tables are the same. Common use and very important graphic characters are retained. The repertoire of this table is optimal for linguistic text processing.

Code table for Windows OS contains the basic repertoire and extra phonetic symbols in 8 and 9 columns. This code table is conformant with 8859-13.

Code table for DOS contains basic repertoire and box drawing symbols and is conformant with IBM CP 775 for Baltic States. DOS environment is still popular in publishing houses.

2.3. Multiple-Octet coding in ISO/IEC 10646-1 (UCS codes)

All letters of main Lithuanian alphabet have UCS codes (codes in ISO/IEC 10646-1) or UNICODE codes. The situation with Lithuanian accented letters is more complicated. As it was mentioned, Lithuanian accented letters are Latin script letters with grave accent, acute accent or tilde. So some Lithuanian accented letters are also the common letters in other languages. For example, LATIN LETTER A WITH ACUTE is also in Irish, Icelandic, Portuguese, Slovak etc. languages, LATIN LETTER N WITH TILDE is also in Basque, Breton and Spanish languages. Thus they have separate UCS codes.

All together there are 33 Lithuanian accented letters which have separate UCS codes and 35 accented letters have not separate UCS codes.

Not shadowed letters have UCS codes; shadowed letters have not UCS codes.

There is another problem with small letter "i" (and "i with ogonek"). Lithuanian letter "i" is with a dot above. All accented forms of "i" should be also with a dot (see samples in 2.4). In ISO/IEC 10646-1 all such forms are dotless. For example, LATIN SMALL LETTER I WITH ACUTE in fact specifies "Latin small letter dotless i with acute". We ought to retain a dot above, in that case, so we should define these letters as LATIN SMALL LETTER I WITH DOT ABOVE AND ACUTE (or may be LATIN SMALL LETTER DOTLESS I WITH DOT ABOVE AND ACUTE).
