I'm using PHP to interface with a legacy console program (not PHP). No big worries doing so. What is weird, however, is when I use the console directly, there is what appears to be a double space when I execute a command and get a specific response. No worries. When I try to display the console dialog in a web browser however, by reading lines from the console, this double space shows up as a black diamond with a white question mark. All other characters display just fine, so I'm not sure what particularly to do. Do I need to process the text in a UTF8 or similar format? Or alternatively, how does one go about determining the hex equivalent of the special character?
