Description: Better reviewed with whitespace ignored Fix #61411 Add support for fatal UTF-8 decoder in no-ICU version unless streaming is used add utf-8 fast path to no-ICU version reduce duplication of TextDecoder source normalize how this[kHandle] was not set in no-ICU version The refactor changes the encoding reported in the no-ICU version when encoding is recognized but unsupported: now the actual resolved encoding name is reported as unsupported when previously the original input string was reported. I don't think this is major, and reporting the actual encoding name is better in that case. This will allow further fixes and common fast path for UTF-16 / fixed impl for UTF-16 as string_decoder doesn't implement UTF-16 per spec. UTF-16 is still broken in no-ICU version here, this PR does not address that. Tracking: #61041
