Greetings,
I have experience in working with "special fonts", please check my portfolio and employers reviews about working on greek and arabic, completely non-standard font. http://www.freelancer.com/u/zezanimator.html so, I am willing to help you to solve this problems, but need more details about problem, specific characters etc. I did not bid on this project because of money, I want to help because I had many similar situations and it is hard to find solution and as big supporter of open source software and linux, just thought to write this and place a bid. Contact me without any obligation.
Best regards, Igor
