MSVC warning about funky characters. #258

Closed gamagan closed 1 year ago

gamagan commented 1 year ago

Hello,

With the latest version as of this writing, 6685012, which is the only one I've tried, I get the following warning on latest MSVC.

The funky chars: \u2502 │ \u250C ┌ \u2514 └o └x 

peglib.h(4687,21): warning C4566: character represented by universal-character-name '\u2502' cannot be represented in the current code page (1252)

peglib.h(4696,65): warning C4566: ... '\u250C' ...
peglib.h(4707,21): warning C4566: ... '\u2502' ...
peglib.h(4709,53): warning C4566: ... '\u2514' ...
peglib.h(4709,63): warning C4566: ... '\u2514' ...

@gamagan, thanks for the report. I just tested it on my machine, but I am not able to reproduce the issue. I get no warning from the VC++ compiler. Here is what I did:

git https://github.com/yhirose/cpp-peglib
mkdir build
cd build
cmake ..
msbuild cpp-peglib.sln

Here is the log when compiling example/calc.cc.

Probably /utf-8 is missing in your project? Hope it helps.
