Glyphs export script for FontLab: error

I tried the "Glyphs export " script before with excellent results. However, the file I am trying to export now – an Arabic typeface – is giving me problems. This is the message I get:

“Traceback (most recent call last):
File “”, line 456, in
File “”, line 450, in main
File “”, line 132, in makePlist
File “/System/Library/Frameworks/Python.framework/Versions/Current/lib/python2.7/encodings /”, line 16, in decode
return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: ‘utf8’ codec can’t decode byte 0xa9 in position 0: invalid start byte”

I don’t have a clue what the problem may be or where to start looking for a solution. Any hints?

Do you have the latest version of the script?
Can you send me the .vfb. The problem is an entry with the wrong encoding. I catched most of them already but I seem to have missed one.

You got it! I just updated the script and it works perfectly. Thanks a lot. Do you still want the file to detect the wrong encoding?

No, if the latest script works, then I already found that problem.
