digitalmars.D.learn - could someone test support for Asian languages in nanogui port?

I port nanogui, but besides porting I'd like to improve it using great 
capabilities of D language provides. One of them is utf support, so I 
added support for Asian languages to nanogui.TextBox. But I'm not sure 
I've did it well and so I'd like to ask someone to test it using the 
following:
```
git clone --recursive https://github.com/drug007/nanogui.git
cd nanogui


```

On the right side there will be a window with four text boxes with 
russian, english, japanese and chinese text respectively. It would be 
nice to get some feedback from users - probably I did something totally 
wrong. Also I'm curious does it worth efforts?

hi, I'm a Chinese, and I just have done the test. I also copied some Japanese text from Dlang twitter channel and added some Chinese wide punctuation Char. And It's all seems displayed correctly. The resulting screenshot is here: https://pasteboard.co/HjRmOYg.png The only problem is that the font style simply looks strange. You can see the 'normal' text display in Win10 by default like this: https://pasteboard.co/HjRrigh.png And the font problem is probably related to SDL or GL, for all UI based on GL or SDL, they all have the same problem. Dlangui also has the same situation, that's why I just did not use Dlangui for a production project. But, Anyway, the text is displayed correctly. Great work for doing this! Dlang needs a great GUI framework.

Can it fixed by other font or there are some other problems?

Could you describe the problem in more details?

SDL probably selects the first font that has the characters, which in his case is a font of comic sans design, instead of a font configured for gui.

It's not the case, the font is set explicitly, so may be other font can solve the problem. Also text is rendered by nanovega, not by SDL. nanovega uses FontStash, lowlevel font engine that in its turn uses either freetype or stb (there are three (!) implementations of it: stb port, arsd and iv, probably all of them just are variants of original std)

yeah, the bad font display can be resolved after setting a CJK font(I just replaced with msyh.ttf). the result is like this: https://pasteboard.co/HQBdP14.png thanks!
