 The angle shape appeared later to increase the distinction and avoid confusions with apostrophes, commas and parentheses in handwritten manuscripts submitted to publishers.Unicode currently does not provide alternate codes for these 6/9 guillemets on the baseline, as they are considered to be form variants of guillemets, implemented in older French typography (such as the Didot font design).Also there was not necessarily any distinction of shape between the opening and closing guillemets, with both types pointing to the right (like today's French closing guillemets).
