This function sets the limit on the number of characters a user can type in or paste into a control.
It also limits the number of characters of RTF text that can be streamed in using
_GUICtrlRichEdit_StreamFromFile() and _GUICtrlRichEdit_StreamFromVar().
It does not limit the amount of plain text that can be streamed in.
The initial limit is 32,767 characters.
