What exactly are you having trouble with? You've been here long enough to know that you should ask a question with enough supporting information. Please review the following for future posts: Ask questions the smart way, I know what I mean. Why don't you? and How (Not) To Ask A Question.

So what code are you having problems with? If it's actually a cut & paste question, then you should direct it to the help group for the OS you're using, or perhaps a PDF support group.

If you have a text file and need to modify it, then I'd suggest making a table-based program to search for problem data and replace it with the data you want. Then, as you find the ligatures, enter the appropriate data in your table and stuff your file through the program.
