Description: PR Summary This PR closes #20614 by applying the kerning algorithm already employed for Type 3 fonts also for Type 42 fonts. For Type 3 fonts, text is broken into chunks to support multibyte chars and to adjust the kerning between chunks. However, previously, a single Tj command was used in the case of Type 42 fonts which results in a text output without kerning. With the PR, the same chunking algorithm is used also on Type 42 text. The new method _font_supports_char is used to decide whether to split the string on an unsupported multibyte char. For Type 42 fonts, the chunks are only used to apply kerning corrections. Multibyte chars are directly referenced without XObjects. There is no change for Type 3 fonts. I'm not even sure if we need the simple Tj case without kerning. Maybe for Type 1 fonts? PR Checklist Has pytest style unit tests (and pytest passes). Is Flake 8 compliant (run flake8 on changed files to check). [N/A] New features are documented, with examples if plot related. Documentation is sphinx and numpydoc compliant (the docs should build without error). Conforms to Matplotlib style conventions (install flake8-docstrings and run flake8 --docstring-convention=all). [N/A] New features have an entry in doc/users/next_whats_new/ (follow instructions in README.rst there). [N/A] API changes documented in doc/api/next_api_changes/ (follow instructions in README.rst there).
