http://dev.w3.org/csswg/css3-fonts/#unicode-range-desc says: ... interval ranges that descend (e.g. U+400-32f) are invalid and omitted rather than treated as parse errors ... Without any valid ranges, the descriptor is omitted. It follows that in the following example unicode-range must be omitted: @font-face { font-family: 'myfont'; src: local('Arial'); unicode-range: U+062-60; } But as of r62096, opening a file containing the above rule results in a crash.

Comment on attachment 60007 [details] Fix for Bug 41339 - unicode-range property only with a descending range causes Can this be tested with a text-only test using getComputedStyle or the CSSOM?

Hi, mitz, Thank you for the review. (In reply to comment #3) > (From update of attachment 60007 [details]) > Can this be tested with a text-only test using getComputedStyle or the CSSOM? I tried but I couldn't find a way to retrieve the actual font name. (I can get 'myfont' but not 'Arial' in the above example). Instead, I used a monospace font and compare the width of two spans. I believe it is good enough for this test.

What I meant was to test the value of documents.styleSheets[0].rules[0].style.unicodeRange, but it looks like there’s insufficient support for unicodeRange values in WebKit’s CSSOM implementation.
