hi all! is there any kind of this feature? when i use permalink, because i use UTF-8 in cagetory name so the cagetory permalink is incorect :( for example: 'Cuộc sống' will be map to cuc-sng in the URL. the post has post slug, so i can define slug and no problem in URL with it; if i have to hack to source, can someone give me some info about it? thanks
