How would you count a base $> 36$ system? When I am counting in a base greater than ten, I can use the letters of the alphabet.  What do I use when I run out of those?
What comes after $z$?:
$0, 1, 2, 3,\ldots, 9, a, b, c, d,\ldots, x, y, z$ (?)
And how would I find it?

We have tons of symbols available, Take any number of languages which have pairways disjoint letters. Index each of those languages and use the pre-ezisting indexes inside the language and you shall have a lot of letters, just by using the symbols for base $10$ numbers ,Japanese Hiragana, katakana, Arab, Hebrew and Spanish we get $179$ symbols.
