Encoder produces broken output for strings starting with a single quote that require escaping

[Aquilosion]

When encoding a string that:

• Requires escaping (e.g. contains a backslash)
• Starts with a single quote

…the stringifier emits a broken multiline token that cannot be parsed back.

Example input:

const Hjson = require('hjson');

const obj = {
    "test": "'Hello,\\nWorld!'"
};

console.log(Hjson.stringify(obj));

Produces this broken output:

{
  test: ''''Hello,\nWorld!''''
}
