Sims 4 Language Strings

The Sims 4 uses "string tables" (STBL files) to store and manage all text displayed in-game, from interaction names to notification pop-ups

The Sims 4 uses a sophisticated system of language strings to handle its massive amount of text across dozens of localized languages.

Never use low, common Hash IDs. Stick to high-range random 64-bit hashes to avoid conflicts.
Always include an English fallback STBL. Even if you speak another language, the Sims 4 community is largely English. An English base ensures your mod works for most testers.
Keep strings short. The UI has limited space. A moodlet string longer than 100 characters might get cut off.
Backup your original STBL files. Before editing EA's core strings, make a copy. One wrong save can require a full game reinstall.
Avoid special characters. While TS4 supports Unicode, some old modding tools corrupt characters like emojis or smart quotes (“ ”). Use plain ASCII where possible.
