Address to Distress

Even more amazingly, I just discovered (from a friend after ranting about this on Facebook) that you're not allowed letters of this type in names on British Passports¹

Apparently there's a recommended transliteration table² from the ICAO that one should use to determine the replacement letter(s).

2025 feels like a very late date to still be conforming to the requirements of teleprinters. I wonder how long this kind of thing will be perpetuated?
