I've always thought that French always requires non-breaking spaces before two-part punctuation characters (e.g. colons, question marks etc.).
Are thin spaces automatically treated like non-breaking spaces? If not, aren't you (theoretically) running the risk that a punctuation character is separated from the preceding word and moved to the next line if the user changes the font size?
BTW, I've read conflicting information regarding the recommended width of a space character before a two-part punctuation character in French. What's the correct width according to your research?
