Details:
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]
------------------------------------------------------------
