cmap-invalid

All codes

• Type: warning
• Kind: input (the input is malformed beyond what tolerance repairs)

What happened

A font’s CMap (its Type 0 /Encoding) or ToUnicode CMap couldn’t be fully used, for one of three reasons:

• entries that can’t be read, which are skipped;
• a predefined CMap Lamina PDF has no table for, read as Identity (Lamina PDF knows only Identity-H/-V and the Uni…-UCS2-…/Uni…-UTF16-… ones);
• a /UseCMap chain deeper than 8 levels, cut there.

Why

A producer bug (bad ranges, a missing end… keyword), or a CJK file using one of Adobe’s character-collection CMaps without embedding it.

How to fix

Nothing to do. The rest of the CMap is used; affected glyphs may extract as other text or U+FFFD.

Example

1 beginbfchar
<0003> <0020
endbfchar

The destination string is not closed; the entry is skipped, and the rest of the ToUnicode CMap is used.

Data fields

None.

The location is object, the font dictionary’s object; none for a direct font dictionary.
