FStringIterator | Unreal Engine 5.7 Documentation

API > API/Plugins > API/Plugins/ElectraBase

There is a known anomaly in the FString::TConstIterator. It iterates all TCHARs in the string including the terminating zero character. This is not the behaviour we want and setup some helper iterator here which is not including the terminating zero.
