TMP font creation and character sets

Hi I'm creating my TMP font assets and I'm not sure how to structure it all and what characters to include.

Some background - We're trying to support 14 languages, players can enter their name and chat with each other. Since at any time a player could be playing with someone else whos name and chat messages are in another language it's going to get complicated. The languages we're localizing in include English, Arabic, Chinese Simplified, Chinese Traditional, French, German, Italian, Japanese, Korean, Portuguese, Russian, Spanish, Thai and Turkish.

1) Since English, French, German, Italian, Portuguese, Spanish and Turkish share a lot of characters I was going to put them in one static TMP font with dynamic fallbacks TMP fonts for Arabic, Chinese Simplified, Chinese Traditional, Japanese, Korean, Russian and Thai. For the other languages like Arabic, I was thinking about having a static TMP font for the most commonly used characters and then dynamic fallbacks for the less frequently used characters, then additional dynamic fallbacks for the other languages. Is this the correct approach?

2) If I have a primary static TMP font for each language which characters should I include? It's simple for languages with a small character set like English but what about Arabic, Chinese Simplified, Chinese Traditional, Japanese, Korean, Russian and Thai?

3) Has anyone used a dynamically populated TMP font using the render mode SDFAA on mobile? What is the performance like?

Hi Frank, thanks for your quick reply

There is a tool to find exactly what characters should be included in the fonts.

I looked into this tool. It's a good start for knowing what to include in my static TMP fonts but I can't rely on it. Using this tool I might miss commonly used characters that players use in their names or chat messages. I would like to avoid TMP fonts being populated at runtime unnecessarily.

For example, Japanese has over 50,000 characters. I need to know which ones to include in the static TMP font on top of what is used in our game. I read that jōyō kanji are commonly used characters so maybe I'll start there.

I was hoping that someone who has done this before could help me out
