# Digraph Unicode Characters Have a Titlecase
Coming from primarily being exposed to the US American alphabet, I'm familiar
with characters that I type into the computer having one of two cases. Either
it is lowercase by default (`c`) or I can hit the shift key to produce the
uppercase version (`C`).
Unicode, which has broad support for character encoding across most languages,
has a couple characters that are called _digraphs_. These are single code
points, but look like they are made up of two characters.
A good example of this is `dž`. And if that character were to appear in an all
uppercase word, then it would display as `DŽ`.
But what if it appears at the beginning of a capitalized word?
That's where _titlecase_ comes into the picture -- `Dž`.
From [wikipedia](https://en.wikipedia.org/wiki/D%C5%BE):
> Note that when the letter is the initial of a capitalised word (like Džungla
> or Džemper, or personal names like Džemal or Džamonja), the ž is not
> uppercase. Only when the whole word is written in uppercase, is the Ž
> capitalised.
(I find it odd that wikipedia's article on this digraph code point is using
separate characters instead of the digraph.)
