Description
JS_PutEscapedString and JS_PutEscapedString write str into buffer escaping any non-printable or non-ASCII character using \escapes for JS string literals. Guarantees that a NUL is at the end of the buffer unless size is 0. Returns the length of the written output, NOT including the NUL. Thus, a return value of size or more means that the output was truncated. If buffer is null, just returns the length of the output. If quote is not 0, it must be a single or double quote character that will quote the output.
