I noticed we're forcing the filenames to Unicode and in my code to copy the tags for the worker I'm extracting them as ASCII as well. I checked and it looks like exiv2 supports Unicode (http://www.exiv2.org/doc/exifcomment_8cpp-example.html) but we should test it etc...
I need the french accents to be supported in paths.
I quickly replaced String::AsciiValue by String::Utf8Value and it works fine for the only command I use (getImageTags) on linux.
Let me know if you plan to work on this and need someone to make tests on linux or windows
Oh that'd be great. You mind opening up a PR? If you could add a test case that'd be even better.
0.5.0 should handle this correctly.
