patch 8.2.1509: vertical separator is cleared when dragging a popup window

Browse Source 
Problem:    Vertical separator is cleared when dragging a popup window using a
            multi-byte character for the border.
Solution:   Only clear the character before the window if it is using a
            multi-byte character. (closes #6766)
