Excellent write up. Learning lots from you.
Same here, we really appreciate it and wish you a success! 
Faerie Solitaire Harvest now supports Simplified Chinese on its Steam version.
It should be pretty cheap for us to support Traditional Chinese too, but we’re not going to do that at the moment. Mostly supporting Simplified Chinese was easy. We used a unique character scanner to only include glyphs needed.
I made a small module for improving natural line breaks for the text. Japanese / Chinese text line breaks - #9 by Pkeod
Some things required language specific adjustments, such as line breaks. For Chinese, we used unique labels for some elements.
Translating FSH is pretty expensive since it has so much lore text but we don’t have expectations of returns from this work. We want to support more languages though. And that’s why in future games we’re making any large batches of text as optional DLC. That way we can ship the main game leaning toward being text minimal, get it translated, and then leave the DLCs in English only until there is enough language specific sales of the main game to justify translating the larger text volumes.
I love the background music.
