Hi Hans, In scrp-cjk.lua, the function "process" can eat some glue node between CJK glyphs. But the following glue nodes between CJK glyph and half_width_open/half_width_close glyphs should not be eaten. For example: \starttext 中国 (Chinese) 的未来 \stoptext Its output need stay the same. Therefore I think the function "process" need add some codes for the test of half_width_open/half_width_close glyphs. This is a patch for it. --- /opt/context/tex/texmf-context/tex/context/base/scrp-cjk.lua 2010-08-20 01:35:20.000000000 +0800 +++ /home/garfileo/scrp-cjk.lua 2010-08-30 17:08:31.000000000 +0800 @@ -553,7 +553,8 @@ if not pcjk or not ncjk or pcjk == "korean" or ncjk == "korean" or pcjk == "other" or ncjk == "other" - or pcjk == "jamo_final" or ncjk == "jamo_initial" then + or pcjk == "jamo_final" or ncjk == "jamo_initial" + or pcjk == "half_width_close" or ncjk == "half_width_open" then previous = "start" else -- if head ~= first then remove_node(head,first,true) -- Best regards, Li Yanrui (李延瑞)
