Shannon Booth	d8759d9656	LibWeb: Use UTF-16 code unit offsets and lengths in CharacterData ... We were previously assuming that the input offsets and lengths were all in raw byte offsets into a UTF-8 string. While internally our String representation may be in UTF-8 from the external world it is seen as UTF-16, with code unit offsets passed through, and used as the returned length. Beforehand, the included test included in this commit would crash ladybird (and otherwise return wrong values). The implementation here is very inefficient, I am sure there is a much smarter way to write it so that we would not need a conversion from UTF-8 to a UTF-16 string (and then back again).

Shannon Booth	1f88046bb2	LibWeb: Add a test for setting and getting Text data ... This is a pretty straightforward test, but I managed to make this crash on real sites while trying to fix #20971 without any other test in the existing suite failing.	2023-12-22 08:19:51 +00:00
Andreas Kling	0d74ced9b5	LibWeb: Don't crash on Document.createElement() with emoji in tag name ... Once again, we were mistakenly using StringBuilder's append(char) when we really wanted append_code_point(u32).	2023-12-04 00:04:04 +01:00
