Use `BLI_strncpy_utf8` & `BLI_snprintf_utf8` for fixed size buffers in DNA and screen data structures such as panels, menus & operators. This could be considered a fix as copying a UTF8 string into a smaller buffer without proper truncation can create an invalid UTF8 sequence. However identifying which of these users are likely to run into would be time consuming and not especially useful.
