This file contained many occurrences of U+F0A7, a character from the
designated Private Use Area, so its meaning is not defined and fonts
can assign any symbol to that character. Since the person who originally
wrote this file works at Microsoft, it seems reasonable to assume that
he was using the Wingdings font, which has a bullet character at U+F0A7.
Thus, replacing these characters with the proper Unicode bullet (U+2022)
seems the right way to fix this.
