proper case and space

[trouvailles]

I have a script that ensures there is always a space after a comma, a space and a capital letter after either a full stop, question mark or exclamation mark. It also removes excess spaces and capitalizes the first letter of a new line.

This works great for me. However, I would also like to use another script that would follow French punctuation rules.

One-part punctuation marks:
These are similar in French and English

Two-part punctuation marks:
In French, a space is required both before and after all two- (or more) part punctuation marks and symbols, including : ; « » ! ? % $ # etc.

Note: The quotation marks (inverted commas) " " don't exist in French; the guillemets « » are used. I don't think that I will ever find a way to change something like "Hi, Jean!" into « Hi, Jean ! ». Anyway, that's another story.

I would be happy with the proper spaces. Here's the script I'm using for English punctuation. Could there be a quick fix to it?

Thanks,

Pierre
