What means
It is a display style of ordinary six, not a new numeral.
Sharp’s MZ-700 was a home computer with a built-in character generator, a stored set of screen shapes. Its European set kept outlined capitals and digits as distinct characters.
Compatibility normalization cleans text by folding some styled characters into plain equivalents. Here it can remove the outline and leave 6; the value stays six.
