Additional Information
strlcslenis Unicode (UTF-8) compliant and will work with Unicode or plain ASCII text fields.- If passed a string argument that is not legal Unicode, it will by default signal an error (configurable as a user preference).
- A corresponding function
bstrlcslencan be used with non-Unicode strings (e.g., binary or legacy encodings).
