all TRichViewEdit methods for inserting one item return boolean value: True if the item was successfully inserted (insertion can fail because of protection). You can use SetCurrent*** methods to set additional properties of this item after the insertion.

support for soft (optional) hyphens (WideChar($AD)) and zero-width spaces (WideChar($200B)) in Unicode text. Normally soft hyphen is invisible. It is displayed as a hyphen only if line breaks is after it.If rvoShowSpecialCharacters is in Options, it is shown as "not" sign (WideChar($AC)), like in MS Word. Unlike spaces and paragraph marks, soft hyphens change their widths when switching normal/show-special-chars modes. So call Reformat when switching these modes. Processing of these characters may slow down formatting of Unicode text. If you do not need them, activate RVDONOTUSESOFTHYPHENS in RV_Defs.inc Zero-width spaces are processed correctly even if this character is not present in the font.

RVF (RichView Format) forward compatibility improved.
