Is it possible to edit Unicode in the free version?
Plain text, drop-down list and text with a button that calls the dialog editor.
Switching the inplace editor to readonly does not work correctly - editing is not available, but when the cell is activated, a Unicode-Ansi transformation occurs and simply leaving the cell, a new text is written.
Property "enabled" is not what we need - we need text selection and a button pressing.
PS The free version is critically important - my project is publicly available with source codes.
