UTF8 support? about imguicolortextedit HOT 8 CLOSED

It is not overly complicated, though it requires some effort to make it work properly. Since there were no requests for it, I did not try to implement it. If there is any demand for it, it might worth it. I will leave this open as a request and see how many are interested in it.

I'd be interested in using it to edit localisation files for https://github.com/Librelancer/Librelancer
This requires UTF-8 though :D

I asked for it because these days I wouldn't write a text editor if it doesn't support UTF8 from the beginning (sooner or later, somebody will open a file with international characters in your editor). I tend to believe that what I really want is Scintilla (yes, a big monster) but running on a OpenGL and/or Vulkan based GUI. Partial ports of Scintilla to OpenGL and ImGui exist, but nobody has done a complete port, AFAIK.

The motivation for this widget is to write an easy to use, user and coder friendly, simple shader/config/script/simple text editing utility, instead of a generic one which tries to cover a very wide range of features. Scintilla is much more complex because of that approach.

I try to keep it small and simple as possible, without bloat, just like ImGui itself. Though, adding UTF-8 support might not compromise the overall simplicity too much, I guess.

I have committed an experimental version of UTF-8 support to dev branch. Please test it. If it gets stable/complete enough I will merge it to master.

Merged #84 to master.

Thanks a lot!! I didn't have the time to look at this before!! I'm in the process of inserting your Win32+DX11 demo into the SDL2 demos, as I have absolutely no idea about Microsoft APIs. I'm a bit surprised about you including the DirectInput header in the demo... what is it used for? I hope I'm doing the surgery right for transplanting it into SDL2... let's see...

EDIT: It worked!! I transplanted it into the SDL2+Vulkan demo quite easily!!

Thanks a lot!! This editor is great!!

Very welcome :) As you might already figured out, the demo is basically a modified ImGui DX11 example, all the includes are coming from that code. The editor itself does not depend on anything like that. It relies on ImGui and STL.
