Code to strip diacritical marks using ICU

Question

Can somebody please provide some sample code to strip diacritical marks (i.e., replace characters having accents, umlauts, etc., with their unaccented, unumlauted, etc., cha

Answer 1

After more searching elsewhere:

UErrorCode status = U_ZERO_ERROR;
UnicodeString result;

// 's16' is the UTF-16 string to have diacritics removed
Normalizer::normalize( s16, UNORM_NFKD, 0, result, status );
if ( U_FAILURE( status ) )
  // complain

// code to convert UTF-16 's16' to UTF-8 std::string 's8' elided

string buf8;
buf8.reserve( s8.length() );
for ( string::const_iterator i = s8.begin(); i != s8.end(); ++i ) {
  char const c = *i;
  if ( isascii( c ) )
    buf8.push_back( c );
}
// result is in buf8

which is O(n).
