Switch test to using our printf

Browse Source 
This test wants to generate a U+FDD2 to see it is not mishandled.

To do so, we tried to use sh, which on my system is bash and can do
`$'\ufdd2'`.

Unfortunately on other systems it might be dash, which won't do that.

Since I don't know of a good no-dependency portable way to generate
this (I dimly remember python3 being a shim on some systems, so I do
not want to invoke it here), we'll just use our own printf.

Which is a worse test, we control both parts, but it'll do.

Fixes #10134
