Wikipedia:
Character pairs encode longitude first, and then latitude.
The first pair (a field) encodes with base 18 and the letters "A" to "R".
The second pair (square) encodes with base 10 and the digits "0" to "9".
The third pair (subsquare) encodes with base 24 and the letters "a" to "x".
The fourth pair (extended square) encodes with base 10 and the digits "0" to "9".
The fifth and subsequent pairs are not formally defined, but recycling the third and fourth
pair algorithms is one possible definition: BL11bh16oo66
