Remove specific character from a string based on hex value

While importing data from a flat file, I noticed that some of lines have embedded non breaking spaces (Hex: A0).

I would like to remove these, but the standard string.replace doesn't seem to work and had considered using regex to replace the string but wouldn't know what the regex would search for to remove it.

Rather than converting the whole string to hex and examining that, is there a better way?

string.Replace does work. Without using RegEx:

stringVar = stringVar.Replace("\xA0", string.Empty);

Would this work for you?

var myNewString = myCurrentString.Replace("\n", string.Empty );
myNewString = myNewString.Replace("\r", string.Empty );

"\n" is ASCII LineFeed, "\r" is Return.

Regex.Replace(input, "\xA0", String.Empty);

This ought to do it.

Why doesn't string.Replace work?

stringVar.Replace((char)0xA0, ' ');
