Base-64 is also just a simple 6-bit encoding using a lookup table ;-) Looking at the code you referenced, it appears that your encoding algorithm is the same as the base-64 algorithm, but your lookup table is slightly different (yours includes space and underscore instead of plus and slash, and the rest are offset by one.) Thanks for the answer.
