I believe so, if there's anything missing from 1.34 let me know.

Iterators yes, no problem.  As for character types you can use:

boost::regex with narrow characters, but not really with multibyte 
sequences.

boost::wregex with wchar_t sequences.

boost::u32regex with any of UTF8, UTF16 or UTF32 sequences (they all get 
converted to 32-bit code points on the fly), but you will need ICU to 
provide the Unicode character database.  See 
http://www.boost.org/libs/regex/doc/icu_strings.html for the docs.

HTH, John.
