UKismetStringLibrary::Len
#include "Kismet/KismetStringLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns the number of characters in the string. Backs the Blueprint "Length" node (compact title LEN).
Caveats & Gotchas
- • Counts UTF-16 code units (TCHARs), not visible glyphs, so combining characters or surrogate-pair Unicode text can report more than one "character" per glyph.
- • An empty string returns 0; use IsEmpty for clearer intent when only checking for emptiness.
