That's because character identity is a hard problem. Is the emoji TIGER the
same as TONY THE TIGER or as TONY THE TIGER GIVING THE VICTORY SIGN?

Note that even in Unicode, the set ẛ ᷥ ſ ṡ s S Ŝ may be considered the
same character or up to seven different characters, depending on
case-folding, canonization and accent dropping.

character. Different documents would represent it differently.

You can index links to images. If two documents represent it differently,
then I go back to the above; we can't know that they're the same thing.

Anytime we care about how much space text takes up, it should be
compressed. It compresses very well. On the other hand, it's rare that
anyone cares anymore; what's a few hundred kilobytes between friends?
