11531	Spirit X3: char_(ch1, ch2) is matching an exclusive range	Adrian Vogelsgesang <vogelsgesang@…>	Joel de Guzman	"In X3 the char_(ch1, ch2) parser is currently matching all characters wich are within the given boundaries but exludes the boundary characters.

This is inconsistent with the documentation which states ""Matches a range of chars from ch to ch2 (inclusive)"".

In addition, I think that qi::char_ is including the range boundaries, too. (I am not sure about this; I did not actually use QI so far and just had a short glance at its source code.)

I think, the error is at this position: [https://github.com/boostorg/spirit/blob/9c5dd09880f24b99e8e694534e532b1bb4a8851a/include/boost/spirit/home/x3/char/char_set.hpp#L45]. The comparisions should be "">= 0"" respectively ""<= 0"".

The testcase in [https://github.com/boostorg/spirit/blob/master/test/x3/char1.cpp] do not test the matching of the boundary characters."	Bugs	closed	To Be Determined	spirit	Boost Development Trunk	Problem	fixed	x3 char_
