The CSV plugin provides an additional table editor (good old Swing component) next to the text editor. While the text editor can show all kind of characters for Thai/Korean, the table editor doesn't (please see issue).
I already fixed an issue by using `UIUtil.getFontWithFallback` to set the font in the table editor, but it didn't solve the issues related to Thai/Korean. I couldn't figure out how the text-editor handles the actual font. Any help is appreciated!
