You can download a working sample( CS, VB). Doing things a character at the time, avoids this problem and allows things to work OK. So, if one char is bold and one is not, then bold is not set when you retrieve the fontstyle for the entire selection. The problem with doing it a whole selection at a time is that the FontStyle of the entire selection is the common styles set among all characters in the selection. Doing it a character at a time will avoid losing the other styles that are set. If you visit the selection a character at the time, you can get the current FontStyle and modify it directly to add or remove a style like Bold or Italic.
