You also caot use ad or i or o or upo which are used ofte i the Eglish laguage. Whe this letter stops workig o a keyboard, it becomes ecessary to copy ad paste that letter frequetly which ofte stops the author from copyig ad pastig other stuff that they wat to copy ad paste, sometimes resultig i pastig a whole block of text or occasioally a web address or phoe umber whe all that is wated is oe little letter.
Missig this letter ca result i cofusio as you ca see. It also results i obvious misspelligs ad grammatical errors.
