--- Comment #7 from Shachar Shemesh shachar@shemesh.biz 2008-11-03 23:36:01 --- ICU was removed because it introduced ABI dependencies into Wine that were unreasonable for general consumption (plus it bloated parts of wine by as much as, if not over, 1000%). As such, any patch that is based on ICU is unlikely to go into the main code.
