----------------------------------------
Summary: PDType0Font return invalid space width
Key: PDFBOX-5920
URL: https://issues.apache.org/jira/browse/PDFBOX-5920
Project: PDFBox
Issue Type: Bug
Components: FontBox
Affects Versions: 3.0.3 PDFBox
Reporter: Miroslav Holubec
Attachments: texgyreheros-regular.ttf
WinAnsiEncoding supports not all available characters from the font. That is
the reason why we moved to the workaround proposed by FAQ, also to use
PDType0Font. Now we have realized, that returned space width from
font.getSpaceWidth() returns invalid value.

jumps over the lazy dog."));
