(Note that this is not IE's behavior for all - // CSS properties, just some sort of special casing for - // font-family). So a single quote *cannot* be used - // safely in the font-family context if there will be an - // innerHTML/cssText translation. Note that Firefox 3.x - // does this too. - // - Double quote. In IE, these get normalized to - // single-quotes, no matter what the encoding. (Fun - // fact, in IE8, the 'content' CSS property gained - // support, where they special cased to preserve encoded - // double quotes, but still translate unadorned double - // quotes into single quotes.) So, because their - // fixpoint behavior is identical to single quotes, they - // cannot be allowed either. Firefox 3.x displays - // single-quote style behavior. - // - Backslashes are reduced by one (so \\ -> \) every - // iteration, so they cannot be used safely. This shows - // up in IE7, IE8 and FF3 - // - Semicolons, commas and backticks are handled properly. - // - The rest of the ASCII punctuation is handled properly. - // We haven't checked what browsers do to unadorned - // versions, but this is not important as long as the - // browser doesn't /remove/ surrounding quotes (as IE does - // for HTML). - // - // With these results in hand, we conclude that there are - // various levels of safety: - // - Paranoid: alphanumeric, spaces and dashes(?) - // - International: Paranoid + non-ASCII Unicode - // - Edgy: Everything except quotes, backslashes - // - NoJS: Standards compliance, e.g. sod IE. Note that - // with some judicious character escaping (since certain - // types of escaping doesn't work) this is theoretically - // OK as long as innerHTML/cssText is not called. - // We believe that international is a reasonable default - // (that we will implement now), and once we do more - // extensive research, we may feel comfortable with dropping - // it down to edgy. - - // Edgy: alphanumeric, spaces, dashes, underscores and Unicode.
