In there is a special character (the sixteenth letter in the Polish alphabet) that display fine on the post, but when the content is downloaded to a PDF, that letter is changed to a "?". I tried switching the font of the printer friendly file, but that didn't help. I also used another PDF plugin but that didn't work either. the letter is: ł. Is there any special encoding for this?

For the record, the site is using wp-post-to-pdf to generate PDFs.

I looked around for other reports of similar issues, and found something in the readme of wp-post-to-pdf-enhanced:

= Non-English characters (Cyrillic, etc.) are shown as "?" in the PDF. What's wrong? =

The default fonts used are Helvetica, which is a core (built into most PDF viewers) font, but not a Unicode font. This avoids downloading the entire font package. However, if you find that your text is not rendering, try a DejaVu font first, before reporting this as a bug. You may set this in the options panel.

I went to and changed the body text to Arial Unicode and flushed the PDF cache, and now the characters are rendering in the PDF as I would expect them. Can you confirm this one way or another?
