Uh, whatever that formatting you're proposing is, it's not UTF-8. Space is not something that is UTF-8 encoded. In fact, none of the lower 128 base ascii bytes should encode.

For UTF-8 encoding you should use System.Text.Encoding.UTF8. Something like this:

string Text = "This is some text - æ I ¢ üì";
byte[] Buffer = Encoding.UTF8.GetBytes(Text);
string Utf8String = Encoding.UTF8.GetString(Buffer);

In fact the string returned from the above will be something very ugly (probably won't show correctly here):

This is some text - æ I ¢ üì

You can apply additional encoding to that string after the fact, but I don't recognize what type of encoding you're using there...

HtmlEncoding will yield:

This is some text - æ I ¢ üì
