LTT, encodings that the character code dialog have not implemented left the status bar character value blank. For example, UTF-7 is not implemented, so the character code value is blank. I have changed it so that if the encoding isn’t implemented yet, and the status bar would be blank, the Unicode value appears instead.
When you first found that the character code value is blank inside the status bar, (link to comment) which encoding where you using? I may implement this encoding if it is well used.
