Help pleaseI am using xpressive for text processing with regexes.Microsoft
Visual C++ 13.0 on a windows 10 laptop, boost version 1_59_0 (and
lib64-msvc-12.0 downloaded from sourceforge) , locale is en_US.UTF-8 .my
regular expressions for catching any and all digits :wsregex
any_number_regex = wsregex::compile(L"^(.*\\D)?(\\d+)(\\D.*)?$");Looks like
it recognizes the superscript 2 and superscript 3  as plain “digits”all
other superscript digits are not caught by this regex.examples:πr² 234³is
this intentional?is this a bug?(I know I can change the regex to catch
[0-9]+, this regex just one of many I use in my software!)thank youMia
