I've created a patch to support this, and tested it on MAME, which makes fairly heavy use of C++14 digit grouping. I'm attaching it as a git changeset.

(file #41365)

xgettext doesn't support C++14's "Single-quotation-mark as a digit separator" feature[1] properly. It'll issue a warning about an "unterminated character constant" with the following trivial program:

------------------------------------------------------------
int main() {
auto i = 1'234;
return 0;
}
------------------------------------------------------------

Invoke xgettext:

------------------------------------------------------------
[0 mosu@sweet-chili ~/test] xgettext -o test.pot test2.cpp
test2.cpp:2: warning: unterminated character constant
------------------------------------------------------------

If you want to verify that this is an actually valid C++14 program:

------------------------------------------------------------
[0 mosu@sweet-chili ~/test] g++ -std=c++14 -o test2 test2.cpp
[0 mosu@sweet-chili ~/test]
------------------------------------------------------------
