Double quotes (or speech marks)
PrintableASCII 34 | Hex 0x22 | U+0022
Paired quotation marks at ASCII 34 delimit string literals in C, JSON, HTML attributes, and CSV fields. JSON requires double quotes exclusively, rejecting single quotes as invalid syntax. In CSV parsing, a literal double quote inside a quoted field must be escaped by doubling it (""). Unicode added distinct left and right curly quotes (U+201C and U+201D), but ASCII 34 remains the only quote character valid in most programming contexts.
