Steps to reproduce:
Demo: https://codesandbox.io/s/suspicious-euler-flddq6?file=/src/index.js:0-729
const alpha = Array.from(Array(26)).map((e, i) => i + 65);
const alphabet = [
...alpha.map((x) => String.fromCharCode(x)),
...alpha.map((x) => String.fromCharCode(x).toUpperCase())
];
const polishLetters = (
"ą,ć,ę,ł,ń,ó,ś,ź,ż," + "ą,ć,ę,ł,ń,ó,ś,ź,ż".toUpperCase()
).split(",");
const result = [];
alphabet.forEach((letter) => {
polishLetters.forEach((pLetter) => {
alphabet.forEach((sLetter) => {
const toCheck = letter + sLetter;
const wrongResult = letter + pLetter;
if (toCheck.indexOf(wrongResult) === 0) {
result.push(${toCheck} === ${wrongResult}\n
);
}
});
});
});
console.log(
[...new Set(result)].toString().replaceAll(",", "")
);

console output is:

Bug 1801690 - Fix searching for 2 wide chars in a latin1 string r?iain
Beta/Release Uplift Approval Request
- User impact if declined: Checking a string for the presence of a two-character sequence could under very specific circumstances yield a false positive.
- Is this code covered by automated tests?: Yes
- Has the fix been verified in Nightly?: Yes
- Needs manual test from QE?: No
- If yes, steps to reproduce:
- List of other uplifts needed: None
- Risk to taking this patch: Low
- Why is the change risky/not risky? (and alternatives if risky): It's basically a one-liner which is pretty trivial to assess for correctness.
- String changes made/needed:
- Is Android affected?: Yes
