UBlueprintPathsLibrary::GetInvalidFileSystemChars
#include "Kismet/BlueprintPathsLibrary.h"
Access: public
Specifiers: staticBlueprintPure
Description
Returns a string containing every character considered invalid in a filename by the current operating system.
Caveats & Gotchas
- • The set of characters returned is platform-dependent — Windows disallows more characters (e.g. `:`, `*`, `?`) than Unix-like systems.
- • This returns a character set for you to filter with yourself; it doesn't sanitize a string for you — use MakeValidFileName for that.
- • The result is a flat string of characters, not an array; to test a character you check for its presence with FString::Contains or similar.
