Legacy Character Replacement
Currently, the "..." chat continuation sign uses legacy characters, which are blurry and do not support drop shadows.
This branch replaces the legacy characters with three ASCII periods (=ellipsis), for the following reasons:
- they are rendered in the same quality as the rest of the font
- ASCII characters are supported by any (sensible) font and do not need a special case for disabled UTF-8, unlike e.g. the interpunct (U+00B7)
- they make more sense semantically
