I use a ctrl-XXXX code for the first character of my master password in password agent 2017. from time to time (can't seem to nail down exactly under what circumstances) the first character of my password is visible and when it is; it never fails to fail unlocking my account. I have to close the file and re-open to correct. not such a big deal however people spying on my screen would be able to see which control code character i'm using as the first character in my password. you said you were all about security and i believe this is an issue. not sure if ctrl codes could possibly be visible anywhere else in the master password or in any of the password fields of any entries; something you'll have to look into yourself ahto. thanks for making a great product. good day.
Do you mean you use Unicode symbol that you enter by holding down Alt + enter 4-digit number from numeric keypad? What happens when you try this on a web page in web browser in a masked password field? I suspects it behaves the same way as in PA?
