[02095ae]248    of the various problems that arise due to application programmers making
[755f44a]249    assumptions that break in such locales, CLFS should not be used in locales
[02095ae]250    that utilize multibyte character sets (including UTF-8) or right-to-left
251    writing order.  Numerous unofficial and unstable patches are required to
[755f44a]252    fix these problems, and it has been decided by the CLFS developers not to
[02095ae]253    support such complex locales at this time. This applies to the ja_JP and
254    fa_IR locales as well&mdash;they have been installed only for GCC and
255    Gettext tests to pass, and the <command>watch</command> program (part of
256    the Procps package) does not work properly in them. Various attempts to
257    circumvent these restrictions are documented in internationalization-related
