title: Does POSIX regex.h provide unicode or basically non-ascii characters?
body: <p>Hi i am using Standard Regex Library (regcomp, regexec..). But now on demand i should add unicode support to my codes for regular expressions. </p>
  
  <p>Does Standard Regex Library provide unicode or basically non-ascii characters? I researched on the Web, and think not. </p>
  
  <p>My project is resource critic therefore i don't want to use large libraries for it (ICU and Boost.Regex).</p>
  
  <p>Any help would be appreciated..</p>
