I haven't yet tracked down which codepoint (glyph) this is; GtkEntry::PROP_INVISIBLE_CHAR claims that it is initialised to '*' (asterisk) but that's clearly not the case. It is presumably one of:
· (U+00B7 MIDDLE DOT) • (U+2022 BULLET) ∙ (U+2219 BULLET OPERATOR)
but is probably being overridden somewhere in the gksu/libgksu source code.
