patch 8.0.0250: virtcol() does not work well for multi-byte charactersv8.0.0250
Problem: When virtcol() gets a column that is not the first byte of a
multi-byte character the result is unpredictable. (Christian
Ludwig)
Solution: Correct the column to the first byte of a multi-byte character.
Change the utf-8 test to new style.
