Dear Pymol users,

I installed Pymol 1.2 on Ubuntu 9.1 but I have the error as the following for all PDB files.
(Select File -> open from the user menu, and select and open that PDB file).

Error: 1
<type 'exceptions.UnicodeEncodeError'> Exception in Tk callback
  Function: <bound method Normal.file_open of <pmg_tk.skins.normal.Normal instance at 0x9f3270c>> (type: <type 'instancemethod'>)

    return _active[_get_ident()]
<type 'exceptions.UnicodeEncodeError'>: 'ascii' codec can't encode character u'\xfc' in position 13: ordinal not in range(128)

What should I do?

Thanks in advance
