Re: [Boost-Users] Re: regex with double byte character sets

DBCS encodings like SJIS are variable-width. But the real problem is that given an iterator into a DBCS string, it is impossible to tell where the previous character starts without walking back to the beginning of the string. So you can really only make a forward DBCS iterator, not a bidirectional one. And I think regex++ requires bidirectional iterators, right John?

Yes that's right, obviously my understanding of DBCS strings was flawed. John Maddock http://ourworld.compuserve.com/homepages/john_maddock/index.htm
