In Opera 7.54 those characters show up as "not in this font" empty square boxes. The emailed version had a bunch of '=xx' codes which I can't read without consulting a Unicode chart: "=E6=97=A5=E6=9C=AC=E8=AA=9E=EF=BC=9F" -- twelve codes for four characters, so in addition to looking at the chart I need a quick refresher on the various ways Unicode is re-encoded for 8-bit environments.

As for two spaces after a period, yah, me too.
