UTF-8 problems while reading CSV file with fgetcsv

Question

I try to read a CSV and echo the content. But the content displays the characters wrong.

Mäx Müstermänn -> Mäx Müstermänn

Encoding of the CSV file is UT

Answer 1

In my case the source file has windows-1250 encoding and iconv prints tons of notices about illegal characters in input string...

So this solution helped me a lot:

/**
 * getting CSV array with UTF-8 encoding
 *
 * @param   resource    &$handle
 * @param   integer     $length
 * @param   string      $separator
 *
 * @return  array|false
 */
private function fgetcsvUTF8(&$handle, $length, $separator = ';')
{
    if (($buffer = fgets($handle, $length)) !== false)
    {
        $buffer = $this->autoUTF($buffer);
        return str_getcsv($buffer, $separator);
    }
    return false;
}

/**
 * automatic convertion windows-1250 and iso-8859-2 info utf-8 string
 *
 * @param   string  $s
 *
 * @return  string
 */
private function autoUTF($s)
{
    // detect UTF-8
    if (preg_match('#[\x80-\x{1FF}\x{2000}-\x{3FFF}]#u', $s))
        return $s;

    // detect WINDOWS-1250
    if (preg_match('#[\x7F-\x9F\xBC]#', $s))
        return iconv('WINDOWS-1250', 'UTF-8', $s);

    // assume ISO-8859-2
    return iconv('ISO-8859-2', 'UTF-8', $s);
}

Response to @manvel's answer - use str_getcsv instead of explode - because of cases like this:

some;nice;value;"and;here;comes;combinated;value";and;some;others

explode will explode string into parts:

some
nice
value
"and
here
comes
combinated
value"
and
some
others

but str_getcsv will explode string into parts:

some
nice
value
and;here;comes;combinated;value
and
some
others
