iText: Compare font after processing string using FontSelector

tl;dr: In iText, is there a way to access the font's name, or figure out the language of a font that has been applied to a Phrase from a FontSelector?

This question is in relation to an issue we've been having for the printwikipedia project --- github -- issue .

I have a body of text that I do not have control over coming in to a FontSelector to be processed. Some of that text is in Arabic and some is in Hebrew and I am trying to figure out the best way of detecting the type of font in order to have it print correctly as seen here: http://developers.itextpdf.com/question/how-create-persian-content-pdf using 

pdfCell.setRunDirection(PdfWriter.RUN_DIRECTION_RTL);

After running the strings through the FontSelector to become Phrases and then placing them within the cell formatted with the code above all the text ends up on the right.

Formatting of this text is very important so I cannot have all of my text aligned to the right but only when it is meant to be read as right to left. So what I believe should be the best course of action is to detect the font that has been applied to the Phrase and then alter the cell if necessary.

public FontSelector fs = new FontSelector();
// add a whole lot of fonts to fs
// incoming line of some sort of text
Phrase ph = fs.process(line);
System.out.println(ph.getFont().toString());

The above code will output some extremely varied results. Pretty much a new id for every font created for each piece of text. I can't figure out a way to compare a font that exists in the fontselector object with a font that has been applied to the incoming text.

Is this the best method to figure out what fonts are in a phrase?

How can I access the font's name, or figure out the language of a font that has been applied to a Phrase from a FontSelector?

I went through the itext documentation a bit more carefully and discovered my answer.

Phrases are made up of Chunks which contain the fonts. If one simple does a .getChunks() command on the output phrase and then iterators over the chunks they can then compare the fonts by doings a .getFont() on the chunks in the arraylist and proceeding to apply whatever styles you wish from there.
