don't understand Qt's setCodecForCStrings

Code:

---

QApplication app(argc, argv);
   QTextCodec::setCodecForCStrings(QTextCodec::codecForName("windows-1252"));
   QTextCodec::setCodecForLocale(QTextCodec::codecForName("windows-1252"));
 
//...

---

Using this code I can display and 'e' with acute by calling

Code:

---

QMessageBox::about (this,"About",QString::fromLocal8Bit("\xe9"));

---

but "\xe1" for an 'a' with acute won't work.
On Windows, I get a compiler warning, saying that "hex escape sequence out of range".
Any workarounds?

Sorry, this was a simple problem. I had a non-hex letter after e acute, and a hex letter after a acute, like "\xe1bbbbbb". The solution: "\xe1" "bbbbbb"
