Email from China has a weird font I can't change?

[Lulubelle]

I have a friend who is visiting China and when she emails me, it's in the MS Gothic font, which is hard to read. When I hit reply, I try to change the font so that I can read it, but it refuses to change. I even copy and paste the text into a blank .txt document, hoping that will strip away the formatting, but it doesn't. She has no idea what do to from her end, so it's left up to me to figure out.

Here is an example of what it looks like:

"Ｃｏｕｌｄ　ｙｏｕ　ｓｅｅ　ｗｈｏ ｔｈｅｙ　ａｒｅ　ｆｒｏｍ?"

Even pasting it here in this window carries the font with it.
