-----------------------------------------

We have SymbolEncoding which seems to be the same. Please share the PDF.

> 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)"
