Constantine Dokolas updated PDFBOX-6004:
----------------------------------------
Description:
I've encountered a PDF with a font named "SymbolMT" which defines its encoding
as {{{}SymbolSetEncoding{}}}. Using the debugger app, I get a warning
({{{}Warning [PDSimpleFont] Unknown encoding: SymbolSetEncoding{}}}) and
multiple {{No Unicode mapping ...}} warnings.
I couldn't find official documentation for this encoding, but the {{pdf.js}}
project has support for this encoding implemented [here
|https://github.com/mozilla/pdf.js/blob/6f052312d625224173db36d3e661657a89cf1865/src/core/encodings.js#L207]
and it looks correct at first glance.
Perhaps it's possible to support this encoding?
Notes
* I've not tested text extraction with PDFBox to see what codepoints are
generated, but Adobe Acrobat converts those codes to the box char (the
"unknown" char?)
* The pdfdebugger app font viewer says: "Encoding: BuiltInEncoding / built in
(TTF)"
