A faster ASCII table

[tabstop]

Where did the 154 come from? 256 / 2 = 128.

154-128 = 26, which seems significant.

Sorry if I was unclear, I meant 154 unique characters.
128 + 26 from replacing a-z with A-Z in the upper half.

I was talking about an 8-bit byte, of which ASCII only defines 7 bits, so you've already got a free bit to play with, so why not make use of it?

Hmm okey I didn't know the standard only defined 7 bits. I thought the 8th bit extension was an accepted addition to the standard. I apologize if I was wrong.
