The illegal character is not in  matches 1   but in  xml  Try  iconv  matches 1    utf-8  TRANSLIT    xml     And showing us the input string would be nice for a better answer

BE VERY CAREFUL  the problem may come from multibytes encoding and inappropriate PHP functions used      It was the case for me and it took me a while to figure it out   For example  I get the a string from MySQL using utf8mb4  very common now to encode emojis     formattedString   strtolower  stringFromMysql    strCleaned   iconv  UTF-8    utf-8  TRANSLIT    formattedString      WILL RETURN THE ERROR  Detected an illegal character in input string       The problem does not stand in iconv   but stands in strtolower     in this case    The appropriate way is to use Multibyte String Functions mb strtolower   instead of strtolower     formattedString   mb strtolower  stringFromMysql    strCleaned   iconv  UTF-8    utf-8  TRANSLIT    formattedString      WORK FINE     MORE INFO  More examples of this issue are available at this SO answer  PHP Manual on the Multibyte String

If you used the accepted answer  however  you will still receive the PHP Notice if a character in your input string cannot be transliterated    lt  php  cp1252        for   i   128   i  lt  256   i           cp1252    chr  i      echo iconv  cp1252    utf-8  TRANSLIT    cp1252    PHP Notice   iconv    Detected an illegal character in input string in CP1252 php on line 8  Notice  iconv    Detected an illegal character in input string in CP1252 php on line 8   So you should use IGNORE  which will ignore what can t be transliterated   echo iconv  cp1252    utf-8  IGNORE    cp1252
