From: oCameLo oTnTh <redmine@...> Date: 2010-11-19T19:10:00+09:00 Subject: [ruby-core:33256] [Ruby 1.9-Feature#4073][Open] HKSCS-2008 Feature #4073: HKSCS-2008 http://redmine.ruby-lang.org/issues/show/4073 Author: oCameLo oTnTh Status: Open, Priority: Normal Category: M17N, Target version: 1.9.2 I suspect that Big5-HKSCS in Ruby missed out some mappings during use it, so I extracted a Big5-HKSCS conversion table from c_951.nls (HKSCS-2001, [1]) and used it to check big5-hkscs-tbl.rb. Except the characters were assigned to PUA in HKSCS-2001, the tbl file missed out 8 characters: cF9E9 => u255E # '���' cF9EA => u256A # '���' cF9EB => u2561 # '���' cF9F9 => u2550 # '���' cF9FA => u256D # '���' cF9FB => u256E # '���' cF9FC => u2570 # '���' cF9FD => u256F # '���' And these 8 characters were included in CP951 but not in the tbl file: cA15A => u2574 # '���' cA1C3 => uFFE3 # '���' cA1C5 => u02CD # '��' cA1FE => uFF0F # '���' cA240 => uFF3C # '���' cA2CC => u5341 # '���' cA2CE => u5345 # '���' cA3E1 => u20AC # '���' HKSCS is just a supplementary set of Big5, but they didn't finger out which kind of Big5 base on. Consider for compatibility, I think CP951 is a good choice. Also, HKSCS-2008 ([2]) was released for a long time. So I tried to combine CP951 and HKSCS-2008 together to make a new tbl file, but I met some problems. First, HKSCS-2008 included 3 ligatures: c8862 => <00CA,0304> c8864 => <00CA,030C> c88A3 => <00EA,0304> c88A5 => <00EA,030C> Does Ruby support this, if so, how to code? Then, these mappings were included in CP951: cA2CC, cA451 => u5341 cA2CE, cA4CA => u5345 cA2A5, cF9E9 => u255E cA2A6, cF9EA => u256A cA2A7, cF9EB => u2561 cA2A4, cF9F9 => u2550 cA27E, cF9FA => u256D cA2A1, cF9FB => u256E cA2A2, cF9FC => u2570 cA2A3, cF9FD => u256F u5341 => cA451 u5345 => cA4CA u255E => cF9E9 u256A => cF9EA u2561 => cF9EB u2550 => cF9F9 u256D => cF9FA u256E => cF9FB u2570 => cF9FC u256F => cF9FD Same question, does Ruby support this, if so, how to code?
