revert(clafrica): whitespaces as allowed chacracters

[pythonbrad]

Undo #61

#61 wasn't a bad idea, but it's better for us to stay with the management of words.
The white-spaces often result in breaking depending of the text area.
And it will not easy to manage the previous transformation in the buffer.
