You will find the content of your selection in the TM variable  
TM_SELECTED_TEXT. Now is up to you, what kind of programming language  
do you prefer and what encoding to you need.

in bash: echo "$TM_SELECTED_TEXT" | wc -c

in Perl: length($ENV['TM_SELECTED_TEXT'])

etc.

If you have to deal with utf-8 then one solution would be to use  
Ruby's/Perl's split(//u) function
...

Or you can calculate the length by using the TM variables:

TM_LINE_INDEX - TM_INPUT_START_LINE_INDEX

this only works for ASCII

...

You can use 'Filter through command'
Input: Selection
Command: wc -c
Output: Show Tool Tip

#this works for ascii



etc....
