An example was given in the very same message you are citing: Emacs distinguishes between Latin-1 ä and Latin-2 ä, for Unicode the two characters are the same. Also, the talk about han unification is a hint: Emacs distinguishes between the Chinese and the Japanese version of some characters where Unicode has han-unified them. Clearly, Unicode is a better model of the real world regarding the ä characters: the iso-8859 character sets have explicitly been designed to share characters, so it's right to consider the ä's the same. So regarding the ä characters, it seems it would be a good idea to use Unicode. Alas, that might have the unforeseen consequence that searching isn't possible anymore: hitting C-s followed by a Latin-1 ä will only find Latin-1 äs, whereas hitting C-s followed by a Latin-2 ä will only find Latin-2 äs. So either people with a Latin-1 kbd or people with a Latin-2 kbd won't be able to search the names! All of this can be worked around by enabling the 8859 unification that will come with Emacs 21.4, of course. (ucs-tables.el has been separately released by Dave Love, so the feature can be had on Emacs 21.2, as well.) I understand that XEmacs has the Latin-Unity package for iso-8859 unification. And then, there is han unification... -- Ambibibentists unite! ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Welcome to geek heaven. http://thinkgeek.com/sf _______________________________________________ [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/bbdb-info BBDB Home Page: http://bbdb.sourceforge.net/
