I was working with Visual Studio, learning to work with .asp and .html, when I noticed that it was giving me weird font errors. I was reading a .txt file and out putting it to a text box. It would change some characters to a diamond ? looking thing. At first I thought it was something strange in the code or something about reading the file. Then I started noticing it on my browser on other sites as well. Is this something that others are having trouble with or is it just me?
