Timothy Flynn	b6ff7f4fcc	LibJS: Allow PrimitiveString to be created with a UTF-16 string ... PrimitiveString may currently only be created with a UTF-8 string, and it transcodes on the fly when a UTF-16 string is needed. Allow creating a PrimitiveString from a UTF-16 string to avoid unnecessary transcoding when the caller only wants UTF-16.	2021-08-04 11:18:24 +02:00
Timothy Flynn	4c2cc419f9	LibJS: Decode UTF-16 surrogate pairs during string literal construction ... Rather than deferring this decoding to PrimitiveString, we can decode surrogate pairs when parsing the string. This prevents a string copy when constructing the PrimitiveString.	2021-08-04 11:18:24 +02:00
Timothy Flynn	0c42aece36	LibJS: Transcode UTF-8 strings to UTF-16 and add UTF-16 accessors ... LibJS parses JavaScript as UTF-8, so when creating a string, we must transcode it to UTF-16 to handle encoded surrogate pairs. For example, consider the following string: "\ud83d\ude00" The UTF-8 encoding of this surrogate pair is: 0xf0 0x9f 0x98 0x80 However, LibJS will currently store the two surrogates individually as UTF-8 encoded bytes, rather than combining the pair: 0xed 0xa0 0xb8, 0xed 0xb8 0x80 These are not equivalent. So, as String.prototype becomes UTF-16 aware, this encoding will no longer work for abstractions like strict equality.	2021-07-22 09:10:44 +02:00
