How should escaped unicode characters be handled when using the JSON.parse function?

Currently, I am working with some strings that are being written out as JSON. Within one of these strings lies the character \u001a. Whenever I try to call JSON.parse('"\u001a"'), I encounter the error message

JSON.parse: bad control character in string literal at line 1 column 2 of the JSON data
. Any suggestions on how to handle this particular character effectively?

Thank you for your help!

Answer №1

Perhaps replacing \ with \\ could potentially resolve the issue.

The first code snippet will throw an exception and result in a parsed value of undefined due to a parse error.

try {
    var x = JSON.parse('"\u001a"');
} catch (e) {
    alert('Caught exception: ' + e);
} finally {
    alert('Parsed value: ' + x);
}

The second code snippet successfully alerts the parsed sequence, indicating that the parsing process was successful.

var z = JSON.parse('"\\u001a"');
alert(z);
