   [
      '&#92;','&#x005C;','&brvbar;','!','&quot;','#','$','%','&amp;',"'",'(',')','*','+','-','.','/',
      '0','1','2','3','4','5','6','7','8','9',':',';',
      '&lt;','=','&gt;','?','@',
      'A','B','C','D','E','F','G','H','I','J','K','L','M','N','O',
      'P','Q','R','S','T','U','V','W','X','Y','Z',
      '[',']','^','_','`',

      'q','r','s','t','u','v','w','x','y','z',
      '{','|','}','~',
      "&euro;", "&lsquo;", "&rsquo;", "&ldquo;", "&rdquo;", "&ndash;", "&mdash;", "&iexcl;", "&cent;", "&pound;", "&curren;", "&yen;", "&brvbar;", "&sect;", "&uml;", "&copy;", "&ordf;", "&laquo;", "&not;", "&reg;", "&macr;", "&deg;", "&sup2;", "&sup3;", "&acute;", "&micro;", "&para;", "&middot;", "&cedil;", "&sup1;", "&ordm;", "&raquo;", "&frac14;", "&frac12;", "&frac34;", "&iquest;", "&Agrave;", "&Aacute;", "&Acirc;", "&Atilde;", "&Auml;", "&Aring;", "&AElig;", "&Ccedil;", "&Egrave;", "&Eacute;", "&Ecirc;", "&Euml;", "&Igrave;", "&Iacute;", "&Icirc;", "&Iuml;", "&ETH;", "&Ntilde;", "&Ograve;", "&Oacute;", "&Ocirc;", "&Otilde;", "&Ouml;", "&times;", "&Oslash;", "&Ugrave;", "&Uacute;", "&Ucirc;", "&Uuml;", "&Yacute;", "&THORN;", "&szlig;", "&agrave;", "&aacute;", "&acirc;", "&atilde;", "&auml;", "&aring;", "&aelig;", "&ccedil;", "&egrave;", "&eacute;", "&ecirc;", "&euml;", "&igrave;", "&iacute;", "&icirc;", "&iuml;", "&eth;", "&ntilde;", "&ograve;", "&oacute;", "&ocirc;", "&otilde;", "&ouml;", "&divide;", "&oslash;", "&ugrave;", "&uacute;", "&ucirc;", "&uuml;", "&yacute;", "&thorn;", "&yuml;", "&OElig;", "&oelig;", "&#372;", "&#374", "&#373", "&#375;", "&sbquo;", "&#8219;", "&bdquo;", "&hellip;", "&trade;", "&#9658;", "&bull;", "&rarr;", "&rArr;", "&hArr;", "&diams;", "&asymp;"
   ];

But when i try to insert the antislah the code & #92; is replaced by his value so when i insert in my database the character disappear

Someone have a solution?
