There s a much easier way to do this  using iconv - from the user notes  this seems to be what you want to do  characters transliteration     PHP net User notes  lt  php      string     ABBASABAD        echo iconv  UTF-8    ISO-8859-1  TRANSLIT    string          output   nothing  and you get a notice       echo iconv  UTF-8    ISO-8859-1  IGNORE    string          output  ABBSBD      echo iconv  UTF-8    ISO-8859-1  TRANSLIT  IGNORE    string          output  ABBASABAD        Yay  That s what I wanted    gt    Be very conscientious with your character encodings  so you are keeping the same encoding at all stages in the process - front end  form submission  encoding of the source files  Default encoding in PHP and in forms is ISO-8859-1  before PHP 5 4 where it changed to be UTF8  finally      There s a couple of functions you can play around with for ideas  First is from CakePHP s inflector class  called slug   public static function slug  string   replacement               quotedReplacement   preg quote  replacement              merge   array               s p Ll  p Lm  p Lo  p Lt  p Lu  p Nd   mu    gt                   s      gt   replacement          sprintf      s     s        quotedReplacement   quotedReplacement    gt                   map   self    transliteration    merge      return preg replace array keys  map   array values  map    string       It depends on a self    transliteration array which is similar to what you were doing in your question - you can see the source for inflector on github    Another is a function I use personally  which comes from here   function slugify  text  strict   false         text   html entity decode  text  ENT QUOTES   UTF-8           replace non letter or digits by -      text   preg replace       pL d    u    -    text           trim      text   trim  text   -        setlocale LC CTYPE   en GB utf8           transliterate     if  function exists  iconv               text   iconv  utf-8    us-ascii  TRANSLIT    text                 lowercase      text   strtolower  text          remove unwanted characters      text   preg replace     - w            text       if  empty  text             return  empty               if   strict             text   str replace            text             return  text      What those functions do is transliterate and create  slugs  from arbitrary text input  which is a very very useful thing to have in your toolchest when making web apps  Hope this helps

The string  chain is in the same character encoding as the characters in the array - it s possible  even likely  that the  first name string is in a different encoding  and so those characters don t match  You might want to try using the multibyte string functions instead   Try mb convert encoding  You might also want to try using HTML ENTITIES as the to encoding parameter  then you don t need to worry about how the characters will get converted - it will be very predictable   Assuming your input to this script is in UTF-8  probably not a bad place to start      first name   mb convert encoding  first name   HTML-ENTITIES    UTF-8
