utf-8 to uppercase in Redhat Linux

[Frank Carman]

How can I convert a utf-8 string to uppercase in a Redhat Enterprise 4 server? All cgis are written in C.

i never did it, but the thing is if it has mixed up both single byte and multibyte character in the same string, then all you have to do

is skip the next sequential characters

here is the code

for(i=0;i<stringlenth;)
{
 if(c1>=224)
 {
  i=i+3;
 }
 else if(c1>=192)
 {
  i=i+2;
 }
 else
 {
  if(string[i]>='a' && string[i]<='z')
  {
   string[i]=string[i]-('a'-'A');//I forgot the difference;
  }
  i=i+1;
 }
 
}
