Pattern: Non-standard whitespace character in code

Issue: -

Description

Irregular whitespace characters (like non-breaking spaces, zero-width spaces, or various Unicode spaces) can cause visual inconsistencies and make code harder to maintain. These characters often appear when copying code from word processors or websites.

Examples

Example of incorrect code:

function foo() {　  // Has irregular space
  return 42;
}

const items = ['foo',　'bar'];  // Has irregular space

if (condition) {
  doSomething();⠀⠀// Has irregular spaces
}

Example of correct code:

function foo() {  // Uses regular space
  return 42;
}

const items = ['foo', 'bar'];  // Uses regular space

if (condition) {
  doSomething();  // Uses regular spaces
}
