Error with line 7 in OpenOPC.py

[emcfins]

Error:

Failed to import [...] due to exception: Non-ASCII character '\xc3' in file /lambda/OpenOPC.py on line 7, but no encoding declared; see http://python.org/dev/peps/pep-0263/ for details (OpenOPC.py, line 7)

the é is causing this error - removing the accent over the 'e' should resolve the issue.
Unless there is another work around?
