Why are some characters garbled when exporting my invoices to PDF format?

Some multibyte characters won't convert to PDF properly, including many Arabic and Cyrillic characters. This is a known issue in the software library ProZ.com uses to do this conversion. The library maintainers have scheduled a fix for the next version, but the date when that new version will be released is unknown. When an updated version is available, ProZ.com will upgrade the invoicing system.

Until this is fixed, invoices with multibyte characters that don't appear properly in PDF format can still be printed and viewed in HTML.
