I don't see a need for this in PDFBox. We're on a low level, itext is on a high
level. We don't detect languages. We don't support complex scripts so we can't
output thai correctly anyway.

> Key: PDFBOX-4183
> URL: https://issues.apache.org/jira/browse/PDFBOX-4183
> Project: PDFBox
> Issue Type: New Feature
> Components: FontBox
> Reporter: vikas kumar jagga
> Priority: Major
>
> Problem :- If a single paragraph has fonts of different languages we need to
> detect the language and load the appropriate PDType0Font font file object
> (holding ttf file) supporting that language fonts.
> PDFbox library should provide a class with addFont() method that can hold
> multiple PDType0Font objects (holding different ttf files) so that this
> object holding multiple font files could be loaded in document object. It
> will reduce the overhead to detect the language and then loading that ttf
> file object.
> iText provide this feature with FontSelector class. Below is the sample code
> usage.
