Suggestion: Make CUI Unicode-aware

[alemonmk]

What I want is very similar to what #67 requests. Current behavior is very unfriendly for building automation tools with it. The output field of GUI can be overridden to act like -o of CUI, why not -o of GUI? I can just use the CUI to achieve this, but it is not Unicode-aware, it does not correctly process anything not named in system locale.

I know not much in C++ but I tried to make the CUI Unicode-aware, just

• a _setmode(_fileno(stdout), _O_U16TEXT);,
• string to wstring,
• "string" to L"string",
• printf() to wprintf(),
• also some copy & paste from waifu2x-caffe-gui/MainDialog.cpp,

but:

• I've spent ~15 hours on getting cmake to build caffe on VS 2017
  • I tried your caffe-builder, but the Boost.Build hates VS 2017 toolset and wasted me ~10 hours,
    • Redownloads and unzipping Boost really contribute, even on SSD it's still HELL SLOOOOOOOW.
  • Also tried the windows branch of BVLC/caffe and the Original caffe-builder but since #46 that's my 6 hours gone.
• VS 2015 installer says "no" to my machine by crashing itself every time I launch it,
• The VS 2015 toolset installed with VS 2017 installer is so broken that its own developer command prompt refuse to be useful.
  • But it can be used in VS 2017, what the hell.

This is very frustrating and I don't bother trying again. I may:

• on your request create a pull request with my modified waifu2x-caffe/Source.cpp and leave the testing to you, or
• get a working caffe environment from you so I can test it myself before creating PR, or
• just wait for you to adjust the behavior of -o.

I'm away from coding the next few days so take your time.

EDIT: I managed to get the libs and project to compile with a fresh VM & VS 2015. CUI went through and tested, it works fine. But GUI was stuck with a C2280 in MainDialog.cpp, Line 842. I'm not gonna touch that.

Anyways, here is the commit. https://github.com/alemonmk/waifu2x-caffe/commit/ba4a975ef11937f439287117840a6c085c03ac99 And here is the CUI executable: https://github.com/alemonmk/waifu2x-caffe/releases/download/git-c7d0206%2Bunicode/waifu2x-caffe-cui.exe

Thank you for saving me much headache. :)
