JSON and XML both support UTF-8. Neither supports embedding arbitrary binary data directly, especially if that data is not valid in your current character set

- crabbone 3y agoYou wanted to send zero byte. This is how you send zero byte. You are making unrelated claims now that has nothing to do with your original claim.
- unilynx 3y agoYou can't safely send zero bytes over XML even with UTF-8 encoding. Not in practice: echo '<zero> </zero>' | xmllint - -:1: parser error : xmlParseCharRef: invalid xmlChar value 0 <zero> </zero> ^ printf '<?xml version="1.0" encoding="utf-8"?><zero>\0</zero>' | xmllint - -:1: parser error : Premature end of data in tag zero line 1 <?xml version="1.0" encoding="utf-8"?><zero> ^ And not in theory: https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-well-formed https://www.w3.org/TR/2006/REC-xml11-20060816/#sec-well-form... Character Range [2] Char ::= [#x1-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF] /* any Unicode character, excluding the surrogate blocks, FFFE, and FFFF. */ [2a] RestrictedChar ::= [#x1-#x8] | [#xB-#xC] | [#xE-#x1F] | [#x7F-#x84] | [#x86-#x9F]
- crabbone 3y agoI explained how to do it, and yet you didn't follow instructions, have done something irrelevant, and are now complaining that it doesn't work... well sucks being you, I guess.
