Acrobat Accessibility: Characters in a text object cannot be mapped to Unicode

Report · Jun 27, 2024

Hi there,

As part of my job, I am performing tagging in Acrobat Pro. As I was checking my document in PAC2021, the error message 'Characters in a text object cannot be mapped to Unicode' showed itself. I have no idea how to fix this issue.

Any help is received with great gratitude 🙂

Kind Regards,

Morten

This is very likley a font issue. A "good" font will have a "toUnicode" table that allows you to map a glyph (the "drawing" of one or more characters) back to the Unicode codes involved. For standard characters that is pretty straight forward, but you also have to consider ligatures, where one glyph actually represents more than one character. Without that table, it's impossible to perform that mapping.
