Subject: [PATCH] test-fonts: Allow for 5 digit codes

[why]
The code is hardcoded for 4 (hex-)digit codepoints. If we want to
examine 3 or 5 digit codes it breaks the formatting.

[how]
Switch from \u to \U to allow printing codepoints with more than 4
digits. This works on all machines I tested (Linux/Mac).

Manually pad the codepoint to get a consistent length independent of
actual number of digits. We can not use "%5x" because we want to
underline only the actual digits.
This also makes the output of empty slots nicer because the underline is
skipped if there is no code.
