Lost characters when typing

Hello everyone,

Has anyone encountered the same error as me, when I try to type the first character is lost. Please help me.

Thanks a lot.

What exactly are you typing here? /T (or /B) then /e then /acutecomb through a keyboard shortcut? Or is the third character you type /eacute and the previous two characters disappear?

I type /T (or /B) then /e then /acutecomb then the T or B character disappears
