Well... You could write a long-ass code:

pawn Код:

new string = //your input
new output
for(new i=0; i<sizeof(string); i++)
{
  if(strcmp(i, "A", true) || strcmp(i, "a", true))
  {
    i = "a"
    new currentoutput = output;
    format(output, sizeof(output) + 1, "%s%s", i, currentoutput);
  }
  if(strcmp(i, "B", true) || strcmp(i, "b", true))
  {
    i = "b"
    new currentoutput = output;
    format(output, sizeof(output) + 1, "%s%s", i, currentoutput);
  }
//etc.
}
string = output;
