swc can't handle unescaped \0

[SukkaW]

Describe the bug

I am developing a Rollup plugin based on swc (using swc as a transformer).

Rollup uses \0 as its virtual module identifier, e.g. rollup's commonjs module uses \0commonjsHelpers.js as the name of its virtual module, which would emit lines like this:

import * as commonjsHelpers from "\0commonjsHelpers.js";

However, swc would throw Syntax Error on \0:

     Error: error: Unterminated string constant

  |
1 | import * as commonjsHelpers from "
  |                                  ^



Caused by:
    0: failed to process js file
    1: Syntax Error

Input code

// Minimum reproduction
// Check on repl.it: https://replit.com/@SukkaW/SweetSmallModulus

const { transformSync: swcTransform } = require('@swc/core');
const { transformSync: esbuildTransform } = require('esbuild');

const code = `
import * as commonjsHelpers from "\0commonjsHelpers.js";
`;

try {
  console.log(esbuildTransform(code, {}));
} catch (e) {
  console.trace(e);
}

try {
  console.log(swcTransform(code), {});
} catch (e) {
  console.trace(e);
}

// This is the minimum repro, kaboom!
try {
  console.log(swcTransform(`const a = "\0a"`), {});
} catch (e) {
  console.trace(e);
}

Expected behavior

Shouldn't throw Syntax Error on \0, either escape it (no matter the given target) silently or leave it as it is.
