How To Fix UPE008 - You cannot remap characters of a custom SAPscript font

SAP Error Message - Details

• Message type: E = Error

• Message class: UPE - Unicode Printing Enhancement tools

• Message number: 008

• Message text: You cannot remap characters of a custom SAPscript font

What causes this issue?

You tried to remap one or more characters which are contained in the
custom SAPscript font (i.e. a TrueType font installed by the customer).

System Response

The system does not allow to remap these characters. The entire action
was discarded. Characters supported by a custom SAPscript font always
have priority in a Unicode Reference Device Type.
Example:
A customer has installed the TrueType font "Comic Sans MS" as custom
SAPscript font ZCOMIC. This TrueType font contains a glyph (i.e. a
character shape) for Unicode codepoint U+0021 (exclamation mark). When
editing Unicode Reference Device Types, it is not allowed to replace the
U+0031 character from Comic Sans MS with the character from another
font.

How to fix this error?

When you select characters (i.e. Unicode codepoints) which you want to
assign to another font, make sure you only choose characters which are
currently mapped to a font from the UPE font repository.
Note: Characters which are contained in a custom SAPscript font always
have a font index value of "00".
