- // can be misinterpreted
- // - Dashes rarely occur, but they fairly unproblematic
- // for parsing/rendering purposes.
- // The above characters cover the majority of Western font
- // names.
- // - Arbitrary Unicode characters not in ASCII. Because
- // most parsers give little thought to Unicode, treatment
- // of these codepoints is basically uniform, even for
- // punctuation-like codepoints. These characters can
- // show up in non-Western pages and are supported by most
- // major browsers, for example: "MS 明朝" is a
- // legitimate font-name
- // <http://ja.wikipedia.org/wiki/MS_明朝>. See
- // the CSS3 spec for more examples:
- // <http://www.w3.org/TR/2011/WD-css3-fonts-20110324/localizedfamilynames.png>
- // You can see live samples of these on the Internet:
- // <http://www.google.co.jp/search?q=font-family+MS+明朝|ゴシック>
- // However, most of these fonts have ASCII equivalents:
- // for example, 'MS Mincho', and it's considered
- // professional to use ASCII font names instead of
- // Unicode font names. Thanks Takeshi Terada for
- // providing this information.
- // The following characters, to my knowledge, have not been
- // used to name font names.
- // - Single quote. While theoretically you might find a
- // font name that has a single quote in its name (serving
- // as an apostrophe, e.g. Dave's Scribble), I haven't
- // been able to find any actual examples of this.
- // Internet Explorer's cssText translation (which I
- // believe is invoked by innerHTML) normalizes any
- // quoting to single quotes, and fails to escape single
- // quotes. (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. Use of
- // str(c)spn assumes that the string was already well formed
- // Unicode (which of course it is).
- if (strspn($font, $this->mask) !== strlen($font)) {

-
- // Historical:
- // In the absence of innerHTML/cssText, these ugly
- // transforms don't pose a security risk (as \\ and \"
- // might--these escapes are not supported by most browsers).
- // We could try to be clever and use single-quote wrapping
- // when there is a double quote present, but I have choosen
- // not to implement that. (NOTE: you can reduce the amount
- // of escapes by one depending on what quoting style you use)
- // $font = str_replace('\\', '\\5C ', $font);
