 French uses angle quotation marks (guillemets, or "duck-foot quotes"), adding a 'quarter-em space' within the quotes.However, many people now use the non-breaking space, because the difference between a non-breaking space and a four-per-em is virtually imperceptible (but also because the Unicode quarter-em space is breakable), and the quarter-em glyph is omitted from many fonts.Even more commonly, many people just put a normal (breaking) space between the quotation marks because the non-breaking space cannot be accessed easily from the keyboard; furthermore, many are simply not aware of this typographical refinement.
