I really like eþ (Ðð Ðð
) and þorn (Þþ Þþ
) as letters, I þink they're elegant. (Plus, I'm really simping for ðe design of lowercase eþ (ð), idk why.)
So, in any languages ðat have ðe "th" digraph, I will replace it wiþ ðe respective letter.
For reference, Þ makes ðe "th" sound in "think",
and Ð makes ðe "th" sound in "that".
