unknown-font

All codes

• Type: error
• Kind: usage (the caller misused the API)

What happened

A FontKey was used with a FontRegistry that did not hand it out.

Why

Keys are indices into one registry; each document has its own.

How to fix

Use the key returned by this registry’s add.

Example

let key = registry_a.add(font, EmbedPolicy::Respect)?;
registry_b.encode(key, "Hi")?; // unknown-font: key came from registry_a

Data fields

• key: the key’s index.
