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 -- View this message in context: http://boost.2283326.n4.nabble.com/Xpressive-regex-superscript-2-and-3-parse...
