Wow, that's another of the big issues... I'll test it later today. If you have
the time earlier, could you please test it with the file from PDFBOX-1019 (

> [PATCH] Parser for Type 1 Fonts
> -------------------------------
>
> Key: PDFBOX-1844
> URL: https://issues.apache.org/jira/browse/PDFBOX-1844
> Project: PDFBox
> Issue Type: Improvement
> Components: FontBox
> Affects Versions: 2.0.0
> Reporter: John Hewson
> Labels: patch, rendering
> Attachments: CustomEncoding.java, Token.java,
> Type1CharStringReader.java, Type1Font.java, Type1Glyph2D.java,
> Type1Lexer.java, Type1Mapping.java, Type1Parser.java, latexdemo.pdf,
> test.pdf, type1.patch
>
>
> This patch adds a parser for Type 1 fonts to FontBox and makes use of it in
> PDFBox for rendering Type 1 glyphs. This should fix various issues with the
> JVM crashing and rendering fonts incorrectly.
> It was necessary to modify Type1CharStringParser to handle the
> `callothersubr` command and correctly handle subroutines. Likewise,
> Type1CharString was modified to support "flex".
> This patch does not remove the AWT fallback for non-embedded and standard 14
> fonts because an entirely new fallback system is needed and suitable fonts
> will need to be shipped as part of PDFBox. This needs to be discussed on the
> mailing list and/or in follow-on issue.
> Note: To keep this patch small I have not replaced any of the existing ad-hoc
> Type 1 parsing code in PDType1Font and preflight. Those classes retain their
> original code which can be replaced in subsequent patches/refactoring. I can
> open follow-on issues for these.
> ~~~
