Unicode support for UI

Post by badaa »

Hi,
I just wanted to have SC in my native language (Mongolian) also UTF-8 encoded charset. PChelpware has same issue. See below.

Then I have downloaded SC source, the latest public available version "SC update 2015(Feb)" and checked up.
The project was configured with "Multi-Byte Character Set" which leads the problem. If I have to do things right way, I need to configure it as use Unicode. In this case I got huge number of errors that I have to correct. I fixed until Socket functions and gave up, because I don't want to change low level socket function, which may affect performance. And I had limited time also only one day to do this task!
Then I have done some small hack which converts only UI string into Unicode. The patch:

PS: Where can I download latest version of SC source? The source https://sourceforge.net/p/ultravnc/code ... /UltraVNC/ seems very different. I want to check up some performance issues like mouse pointer etc.

Did you ever find a solution for this? It's really unfortunate that in 2018 SC still doesn't support any language other than English.
