239 | of the various problems that arise due to application programmers making

240 | assumptions that break in such locales, CLFS should not be used in locales

242 | writing order. Numerous unofficial and unstable patches are required to

243 | fix these problems, and it has been decided by the CLFS developers not to
|

244 | support such complex locales at this time. This applies to the ja_JP and
|
---|
245 | fa_IR locales as well—they have been installed only for GCC and
|
---|
246 | Gettext tests to pass, and the <command>watch</command> program (part of
