Hi

I have the following problem: it i make a note in a pdf with my surface pen and with the pencil function, and my notes includes some dots like i- dots and i will remove a part of the note, adobe remove not just the party with i wanna delete it removes also the dots automatically. for example the letter Bianca includes the i and i just wanna remove the B it delets the B and the i-dot!

how can i avoid this ?

need any help please!
