Whatever the origin of the modifier letter apostrophe, if it is not distinguished from the quotation marks, the text becomes illegible. We found that retaining the circular shape of the dot in the comma-shaped 02BC but increasing the size of the character to 140% of the original makes a good, legible character.

  Note that Mark is talking about U+02BC, not U+02BB which, as I
understand, is commonly used to represent the Hawaiian ʻokina.
