1437   UNICODE codepoints greater than U+FFFF not supported

Cause

This error occurs if you attempt to convert a UTF‑8 string that contains a code point greater than U+FFFF to a native character. (The receiving field is not large enough to store that 2‑character value.)

This error also occurs if such a string is attempted to be converted to ANSI. (There is no ANSI representation for Unicode surrogate characters.)

Action

Replace the characters causing the problem in the source UTF‑8 string value.
