Description

Blueprint function library for querying and changing the current culture, language, and locale used for localization and internationalization at runtime.

Caveats & Gotchas

• The class-level BlueprintThreadSafe meta tag doesn't make these calls safe from arbitrary background threads — most mutate global localization state and should be driven from the game thread.
• Changing culture/language/locale at runtime doesn't automatically refresh FText already bound in existing UMG widgets — widgets need to be rebuilt or use a live culture-aware binding to reflect the change.
• SetCurrentCulture and SetCurrentLanguageAndLocale both clear any asset group culture overrides set via SetCurrentAssetGroupCulture — apply asset-group overrides after calling either, not before.

Example

Change the game's language and locale C++

UKismetInternationalizationLibrary::SetCurrentLanguageAndLocale(TEXT("ja"), true);

public	function	UKismetInternationalizationLibrary::GetCultureDisplayName	Returns a human-readable display name for a culture code, either localized into the culture's own language or into the current display language.
public	function	UKismetInternationalizationLibrary::GetCurrentCulture	Returns the current culture as an IETF language tag (e.
public	function	UKismetInternationalizationLibrary::GetCurrentLanguage	Returns the language currently used for localization as an IETF language tag (e.
public	function	UKismetInternationalizationLibrary::GetCurrentLocale	Returns the locale currently used for internationalization (date/number/currency formatting) as an IETF language tag.
public	function	UKismetInternationalizationLibrary::GetLocalizedCultures	Returns the list of cultures that have localization data available, filtered by which resource groups (game, engine, editor, plugins) to check.
public	function	UKismetInternationalizationLibrary::IsCultureRightToLeft	Checks whether a given culture's writing system reads right-to-left (e.
public	function	UKismetInternationalizationLibrary::SetCurrentCulture	Sets both the current language and locale at once from an IETF language tag, and clears any asset group culture overrides.
public	function	UKismetInternationalizationLibrary::SetCurrentLanguageAndLocale	Sets both the current language and locale together from a single IETF language tag, without touching any asset group culture overrides.
public	function	UKismetInternationalizationLibrary::ClearCurrentAssetGroupCulture	Removes a previously set culture override for the given asset group, reverting it to follow the current language.
public	function	UKismetInternationalizationLibrary::GetCurrentAssetGroupCulture	Returns the culture override for a given asset group, or the current language if no override has been set for that group.
public	function	UKismetInternationalizationLibrary::GetNativeCulture	Returns the native (source) culture that a given localization category's text was authored in, before any translation.
public	function	UKismetInternationalizationLibrary::GetSuitableCulture	Finds the best match for CultureToMatch within a list of available cultures using culture prioritization, falling back to FallbackCulture if nothing matches.
public	function	UKismetInternationalizationLibrary::SetCurrentAssetGroupCulture	Overrides the culture used for a specific asset group category, for example choosing English voice-over while the rest of the UI stays in Japanese.
public	function	UKismetInternationalizationLibrary::SetCurrentLanguage	Sets only the current language used for localization (translated text), leaving locale-driven formatting unchanged.
public	function	UKismetInternationalizationLibrary::SetCurrentLocale	Sets only the current locale used for internationalization (date, number, and currency formatting), leaving the display language unchanged.
