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:

The only problem is that the font style simply looks strange. You 
can see the 'normal' text display in Win10 by default like this:

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.
