Oh, not trying to discredit you, I've seen them too.
One of many reasons why I like to stick to the good ol' romance languages (or strings thereof).
You can actually type in other languages that use somewhat of a latin alphabet (a, b, c, d, etc.), the letters with ` or ~ or such above the heads can be inserted with MS Word (Insert > Symbol) or entered with an alt-code (I.e. Alt+168, which is an upside-down question mark: ¿).
