About 4 months ago, I asked you to solve the problem of Korean letters not being displayed. You said that this problem will be solved in the next version, but in V0.5.0, and earlier versions, the Korean letters are still not displayed. (The same goes for Japanese as I've tried.)
Since then, I've done a lot of research at Unity and I think you're using Dynamic Font from TextMeshPro. When using this, I found out that a similar phenomenon occurs when the size of the atlas is small.
The main character of Korean letters is about 2,350 characters. In other words, the width and height of the atlas must be large enough. (Based on sampling point size 64, 4096*2048 is a little short in theory, but this is actually enough.)
I don't think some Korean users, including myself, are the main target of your work, but I don't think this modification will be that difficult and it won't affect other areas of the program too much. I would really appreciate it if you could show me a favor to correct this.
I am using a translator because of my lack of English skills just like last time. There may be inappropriate or disrespectful expressions, but it was never intended. Thanks.
