Then, what about Korean Alphabet(Hangul)? The South Korean Map(NOT South Korean Adventure Map) using Hangul was released three years ago. (Now this is not compatible with 1.35...)

Exotic character ranges like that will most likely only work with image sets. Although a font set could be created with a lot of work. It's not possible for Arabic/Hebrew because the engine has no support for RTL (right-to-left) languages

Well, Korean, Chinese and Japanese are supported languages, and therefore, their character sets are supported as well. Arabic and Hebrew are not supported. So, theoretically, these languages shouldn't be a problem...

Having a sign font with these characters is another question; all sign fonts that are currently available only cover limited ranges, none including the aforementioned languages.

Hello,

I am looking at a possibility of using one of the DE Dynamic Sign panels for signs such as this, but I wish to ask how I can add new colours, and make them illuminate at night as with the existing gantry panels, which use the Swedish ones as the backbone.

Try to look at signage in ProMods Greece, maybe you'll find satisfying board model

Awesome!
