Sims 4 Language Strings Fix: How to Restore Missing Text & Glitched Names

Is your Sims 4 game suddenly speaking in "code"?

Imagine this: You launch your game, excited to play, but instead of "Cook Dinner," the interaction says something like ##4F3A91_PLAY. Or worse, your Sim’s whims are just long strings of random numbers and letters.

This is known as the Language String Error. It is one of the most jarring glitches in The Sims 4, turning your immersive life simulator into a confusing mess of computer code. sims 4 language strings fix

Fortunately, you don’t need to be a modder to fix this. Here is everything you need to know about why this happens and how to fix it.


4.2 Mod Conflict Isolation (The 50/50 Method)

What Are "Language Strings"?

In simple terms, The Sims 4 uses a database of text called "strings" to display words in your chosen language (English, French, German, etc.). When the game tries to call up a phrase like "Flirty" but cannot find the file or the correct translation, it spits out the raw code instead. Sims 4 Language Strings Fix: How to Restore

4. Broken Custom CAS Traits/ Careers

Custom content creators sometimes forget to assign a string table to their mod. The trait works, but the name shows up as SNB_Bank_Overdraft_Feeling_Str because the creator hard-coded a key instead of a proper string.

Step 4: Check Your Game Language (EA App Glitch)

A weird bug switches the game to "English (Legacy)" or a mismatched region. Action: Move all mods to desktop → delete

Step 3: The Registry Fix (For Persistent Wrong Languages)

If your game launches in French when your EA App is in English, your Windows Registry has a conflicting entry.

Warning: Incorrect registry editing can break other programs. Follow exactly.

  1. Press Windows + R, type regedit, press Enter.
  2. Navigate to: HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\EA Games\The Sims 4 (If you don’t see WOW6432Node, check HKEY_LOCAL_MACHINE\SOFTWARE\EA Games\The Sims 4)
  3. On the right panel, double-click the Locale string.
  4. Change the value to your desired language code:
    • en_US – English (US)
    • en_UK – English (UK)
    • fr_FR – French
    • de_DE – German
    • es_ES – Spanish
    • it_IT – Italian
    • nl_NL – Dutch
    • pt_BR – Portuguese (Brazil)
    • pl_PL – Polish
    • ru_RU – Russian
    • ja_JP – Japanese
    • ko_KR – Korean
    • zh_CN – Chinese (Simplified)
    • zh_TW – Chinese (Traditional)
  5. Click OK and close Regedit.

Pro tip: If the Locale key is missing, right-click > New > String Value > Name it Locale > then set the data.

Fix A: The Mod Conflict Resolution (90% of cases)

  1. Update all script mods (MC Command Center, UI Cheats, Better BuildBuy, etc.) – string changes are common in patches.
  2. Use a 50/50 split test:
    • Put half your mods back → launch.
    • If strings break, that half contains the culprit.
    • Narrow down until you find the mod with bad string tables.
  3. Check for duplicate string overrides using Sims 4 Studio (see Step 3 below).
