ibus old version(

the problem hits for long time, fedora 11+ibus1.2.0.20090927,

checked as a known bug on ibus engine, which should have been fixed in ibus1.3.5+ version,

when I checked out source code ibus-1.3.9, failed to continue for glib version,

also seems no patch into the old ibus version, but I’ve no intension to move onto newer kernel platform, considering  to adopt fictx.

两个很有趣的函数,
Soundex(string),
rules on: http://en.wikipedia.org/wiki/Soundex
会将一串字串依英文读音换成拼写形式,规则比较有趣,KNUTH的书…我就先不去挖了

Width_bucket(x,min,max,num_bucket),
将范围(min,max)分为num_bucket节,每节有相同大小。返回x所在的那节。

CIDR
