Why does the French language put spaces before their ending punctuation mark?

I don't know if it's just the French language, but they always seem to put a space before the ending punctuation mark (periods, exclamation marks, question marks) Is there a reason for that? Would it be wrong to write French without the space at the end?

1. Never noticed that. I don´t think they do. they never did in my textbooks.
2. Never seen that either...
3. The rule is the same as in English. You don't need to put a space before any ending ponctuation mark. Someones do that only because they think it's more clear.
4. Hi, it is true that punctuation in English and in French are different, for example with ";", but for the point the rule is French is no space before but a space after, the same in English.
