[Boost-users] [Regex] Japanese character equivalence is not working.

Hi, My name is Raveendra Madala. I work for Adobe Systems. We are using boost/regex 1.33.1 in one of our projects and we have encountered the following bug. Character Equivalence is supposed to find all variations of a given character. When we try to use this with Japanese characters regex is failing. To test this, if we have 0x30A2(Full width Katakana letter A), 0xFF71(Half width katakana letter A) and 0x32D0(Circled Katakana A) in the text and if we enter [[=a=]] where a is katakana a then regex is unable to find the three characters. This is just an example and is happening for all Japanese characters. How can we work around this issue? If you require more information on this, please do let me know. Thanks, Raveendra
