zh-arphicttf's pattern.
Some fonts have problems with X-TT/X-freetype, possibly due to bogus
entries, including wcl-02.ttf, wcl-03.ttf, wcl-05.ttf, wcl-06.ttf, and
wcl-07.ttf. The rest are displayed correctly.
Further testings showed that all these fonts can't be used in GS6. It
seems that the patched GS6 is confused identifying Big5 and GB TTFs,
so for now only the newer Unicode-encoded TTFs can be used.
