Wow I never noticed it before but this must a be a bug, no other phone that I have used has this problem

A single character with a " ´ " will take 91 spaces out of 160!

a single sms containing for example: ó will leave 69 character left to type
but if you include more : áéíóú it will have 65 remaining characters.

I can understand if they use 2 characters per letter, but 91? only for the first one? something must be broken.
