Guardian Procedure Calls Reference Manual

codes from the HP internal character set are mapped to the target nondisplayable character
code.
• The most common definition of an invalid character code is a character pair that is expected
to be a two-byte code but has an invalid first or second byte.
Any character mapped to either a nondisplayable or invalid character target code becomes
nonrecoverable for conversion to the original format.
