boost regex matching question

Question

Hi,

I want to test a regular expression with boost:

const wregex regex_comment(L"^\\s*#.*"); //regexpr for comment 

My problem - it does not match a widestring consisting of: #This is a comment can someone give me a hint why or where I can look for the error?

hm - it seems to work in the non-Unicode version. I'm using boost 1.42, self compiled on VS2010.
