php compile parameter --enable-mbstring only enable janpanese support (details can be found http://cn2.php.net/mbstring) in order to support chinese and korean, the parameter should be changed to --enable-mbstring=all Reproducible: Always Steps to Reproduce: 1. 2. 3.
I wanted to change the correspoding eclass to solve this, but I found an interesting thing: when I echo $myconf just before econf in php.eclass, I found all the compile parameters are specified twice! But I just couldn't figure it out why.
fixed in cvs.
