Problem with show special character (ASCII)-> Advanced Web Server

I have a problem with special character (ASCII-Code >127) in a HTML side. I use the advanced web server and the pbuilder. I want to indicate the temperature in the HTML side (for example 30 °C). If I am insert the special character “°” my HTML side destroyed. Without the special character “°” the side is ok.
This is my code in the file *_v.c:
extern char *temp2(void);
char *temp2(void) {
char * theResult;
sprintf(buff, “%.0f”,a_tu);
strcat(buff," °C"); <<<<< this ist the point “°”
theResult = buff;



I found the solution. The keyword in RpTextType must be set to ASCIIExtended !


Use °
