------- Additional Comments From pablo at mandriva dot com 2006-05-12 10:17 -------
The use of iso14651_t1 by default then only redefine or add some local rules if
needed is indeed much better than redefine everyhing in a locale; as the things
redefined are much smaller, it helps understand the important rules, and more
easily detect errors and correct them.
Also, it also allow sorting in a predictable way the characters out of the scope
of the locale, which is a very nice thing to have.
I attached an improved iso14651_t1 that adds a lot of other latin and cyrillic
characters that were missing, so they get sorted too; it also handles double
accented letters (like in vietnamese); and adds armenian and tifinagh script
blocks; considet de t/s with cedilla and t/s with comma below as synonyms for
sorting and made digraphs (as opposed to ligatures) as synonyms of the base
letters for sorting.
It provides a much better default collating set.
Note that with the exception of t/s with cedilla and t/s with comma below and
the digraphs (which are unicode compatibility stuff and should never be typed
directly btw), I mainly only added new, previously ignored, characters.
The main advantages of that modified file are a proper (or at least, quite
acceptable) sorting, when using a generic (eg not specific to that language)
locale; in particular when sorting words from Armenian, Vietnamese, African or
Native American languages written in latin script, languages of former USSR
written in cyrillic script.
