How to truncate non-ascii characters from string using PHP

ascii, non-ascii-characters, php, preg-replace, utf-8

Solution

Here is a solution to my question. Finally I could able to see the conversion. Some Unicode characters are replaced with some Ascii characters. But after all everything is now working fine.

function toASCII($str)
{
    $accent   = 'ŠŒŽšœžŸ¥µÀÁÂÃÄÅÆÇÈÉÊËÌÍÎÏÐÑÒÓÔÕÖØÙÚÛÜÝÞßàáâãäåæçèéêëìíîïðñòóôõöøùúûýýþÿŔŕƒ';
    $noaccent = 'SOZsozYYuaaaaaaaceeeeiiiidnoooooouuuuybsaaaaaaaceeeeiiiidnoooooouuuyybyRra';
    $string = strtr(utf8_decode($string),utf8_decode($accent),$noaccent);
    return strtr($string, $accent, $noaccent);
}

Problem

I have a following string as a Filename `$string = 'recyclage plétre francin.jpg';` and tried with following code ``` echo preg_replace('/[^a-z0-9|^.]/i', '_', iconv("UTF-8","ISO-8859-1//TRANSLIT",$string)); ``` as there is a special (non-ascii) character in filename it creates junk character while working with file uploading using PHP. What I want is that replace any unicode (non-ascii) character with specific Ascii character. I want to keep all supported Ascii characters and remove non-ascii characters. I also want to keep `/` or `\` slashes because of directory separators in filename where a root path will be given. Edit: (below is not solved) I am having a issue with `recyclage plƒtre francin.JPG` please the `f` character which displays output like `recyclage pl` and it had truncated `.JPG`. Actually file name was `recyclage plâtre francin` and when I was debugging it has shown `recyclage plƒtre francin.JPG` and rest is written just after that. Any Idea? When I am trying to convert `tri et recyclage du plâtre` but when at the reading it shows `tri et recyclage du plâtre` and after conversion it shows `tri et recyclage du pl^atre`. Any help will be appreciated.
