CRT unit and UTF-8 displays

Hello, there is some trouble when the display is set to UTF-8 and my program uses the CRT unit. Some characters are just shown as several spaces or even scramble the display. For example I cannot use the german letter sharp s #$C3#$9F (U+00DF) or german quotation marks #$E2#$80#$9E ... #$E2#$80#$9C (U+201E ... U+201C). It works fine without the CRT unit. Also when I use FreePascal it is all right. I've tried to use the command "SetPCCharset(false);", but that didn't help. Is there anything else I could try? -- AKFoerster
