Character encoding issue

[garciaaa]

There is problem in NativeTextRenderer while using non-english national characters (Russian in my case). Multiline render used in label control shows wrong characters.
It can be fixed adding charset while importing "DrawText" from user32.dll like this:
[DllImport("user32.dll", CharSet = CharSet.Auto)]
instead of
[DllImport("user32.dll")]
I dunno why, but gdi32's TextOut do not cause any problem with charset.
(Russian Win7, Win10, .net 4.x, .net core 3.1)

Hi! Thank you for this info, related to #10. I'll fix this ASAP

To show off problem there are Russian letters shown nearby nearby chinese in #10. Roboto fonts you ship with your great package DOES contain cyrillic (russian) subset

Yeah, I didn't know how to fix it, I never messed with different encoding on the same app, thanks for finding out such an easy fix. Feel free to open a PR
