UKismetTextLibrary::IsPolyglotDataValid

function Engine Blueprint Since unknown

#include "Kismet/KismetTextLibrary.h"

Access: public Specifiers: staticBlueprintPure

Description

Checks whether the given FPolyglotTextData is valid — i.e. has the required identity and source data to produce usable text.

Caveats & Gotchas

• FPolyglotTextData is a design-time construct for authoring multiple language variants of a string inline (typically in code or data assets) rather than through the string table pipeline — this validates that authoring, not a runtime translation lookup.
• ErrorMessage is only meaningful when IsValid is false; it isn't cleared to empty text on the success path.

Signature

static void IsPolyglotDataValid(const FPolyglotTextData& PolyglotData, bool& IsValid, FText& ErrorMessage);

Parameters

Name	Type	Description	Default
PolyglotData	const FPolyglotTextData&	The polyglot data asset/struct to validate.	—
IsValid	bool&	Receives true if the data is valid, false otherwise.	—
ErrorMessage	FText&	Filled in with a human-readable reason when IsValid is false.	—

Return Type

void

Example

Validate polyglot data before converting to text C++

bool bValid;
FText Error;
UKismetTextLibrary::IsPolyglotDataValid(MyPolyglotData, bValid, Error);
if (!bValid)
{
    UE_LOG(LogTemp, Warning, TEXT("Invalid polyglot data: %s"), *Error.ToString());
}
