Especially 'th' is a prominent letter in Elder Futhark, far more widespread
than 't'. It has survived in English as 'þ' until a combination of disdain
from Latin-educated scribes and printing presses imported from Germany that
lacked this letter wiped it out.
Alas, we need to maintain a 1:1 relationship to keep alignment, thus you
need to write 'þ', 'æ' or 'ŋ' (or uppercase). Unless you're Icelandic,
it's easiest to use the Compose key.
