FTextChar

Utility for performing Unicode aware (in builds with ICU enabled) character checks.

API > API/Runtime > API/Runtime/Core

Utility for performing Unicode aware (in builds with ICU enabled) character checks. In builds without ICU enabled (such as server builds), this API uses the non-Unicode aware FChar API internally. The implementation can be found in LegacyText.cpp and ICUText.cpp.
