Base 27 encoding

This is just for lulz.

• Take a character string (ASCII8, no character >242).
• Transform each byte into a sequence of 5 trinary digits (i.e. from 00000 to 22222).
• Concatenate all trinary digits (i.e. a long sequence of 0, 1, and 2).
• Add extra 0s at the end so that the total length is divisible by 3.
• Break down by groups of 3.
• Transform each group of 3 into an integer, ranging from 0 to 26.
• Map 0 to -, and 1 to 26 to A to Z.
• Concatenate the result.

Example:

encode('Hello, world!')
'HAFV-LAJAQCPLVCLSICSCR'
