Not sure if this regex does what you want

[LouisMichael]

Here it seems to be trying to strip out unicode punctuation but \p{} is not a supported python regex feature, it just matches literal p
Example case:

re.sub(ur'\p{P}+', ' ', "apc , f")
'apc , f'
re.sub(ur'\p{P}+', ' ', "apc , f p{P}")
'apc , f '
