This seems to work fine. I guess http://wiki.documentfoundation.org/Development/String_Classes should be updated?

The table lists the following:
xub_StrLen SearchAndReplace( sal_Unicode c, sal_Unicode cRep, xub_StrLen nIndex = 0 );
xub_StrLen SearchAndReplace( const UniString& rStr, const UniString& rRepStr, xub_StrLen nIndex = 0 );
xub_StrLen SearchAndReplace( const sal_Unicode* pCharStr, const UniString& rRepStr, xub_StrLen nIndex = 0 );
xub_StrLen SearchAndReplaceAscii( const sal_Char* pAsciiStr, const UniString& rRepStr, xub_StrLen nIndex = 0 );
void SearchAndReplaceAll( sal_Unicode c, sal_Unicode cRep );
void SearchAndReplaceAll( const UniString& rStr, const UniString& rRepStr );
void SearchAndReplaceAll( const sal_Unicode* pCharStr, const UniString& rRepStr );
void SearchAndReplaceAllAscii( const sal_Char* pAsciiStr, const UniString& rRepStr );
