No, it's not about G-spot.
Adds g2 mapping. It prints binary values of the bytes used in the character
under the cursor, assuming it is in
UTF-8 encoding. This
also shows composing characters.
Example of a character with two composing characters:
01100101 + 11001100 10000001 + 11001101 10000101
The g2 mapping is equivalent to vim's builtin
g8,
it just shows binary instead of hex values.
