Hi,
Similar to the Spanish override there, we added a CVar for this in 5.4:
Localization.UseLocaleSpecificDigitCharactersIf you’re on an older engine version at the moment, you can grab CL# 27852750 and set that CVar to false. That should be a pretty straightforward change to cherrypick, but let us know if you run into any issues.
Best,
Cody
