UTF8 Encoding problem - With good examples

This may be a job for the mb_detect_encoding() function.

In my limited experience with it, it's not 100% reliable when used as a generic "encoding sniffer" - It checks for the presence of certain characters and byte values to make an educated guess - but in this narrow case (it'll need to distinguish just between UTF-8 and ISO-8859-1 ) it should work.

<?php
$text = $entity['Entity']['title'];

echo 'Original : ', $text."<br />";
$enc = mb_detect_encoding($text, "UTF-8,ISO-8859-1");

echo 'Detected encoding '.$enc."<br />";

echo 'Fixed result: '.iconv(text)."<br />";

?>

you may get incorrect results for strings that do not contain special characters, but that is not a problem.

I made a function that addresses all this issues. It´s called Encoding::toUTF8().

<?php
$text = $entity['Entity']['title'];
echo 'Original : ', $text."<br />";
echo 'Encoding::toUTF8 : ', Encoding::toUTF8($text)."<br />";
?>

Output:

Original : France Télécom
Encoding::toUTF8 : France Télécom

Original : Cond� Nast Publications
Encoding::toUTF8 : Condé Nast Publications

You dont need to know what the encoding of your strings is as long as you know it is either on Latin1 (iso 8859-1), Windows-1252 or UTF8. The string can have a mix of them too.

Encoding::toUTF8() will convert everything to UTF8.

I did it because a service was giving me a feed of data all messed up, mixing UTF8 and Latin1 in the same string.

Usage:

$utf8_string = Encoding::toUTF8($utf8_or_latin1_or_mixed_string);

$latin1_string = Encoding::toLatin1($utf8_or_latin1_or_mixed_string);

I've included another function, Encoding::fixUFT8(), wich will fix every UTF8 string that looks garbled.

Usage:

$utf8_string = Encoding::fixUTF8($garbled_utf8_string);

Examples:

echo Encoding::fixUTF8("FÃ©dÃ©ration Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂ©dÃÂ©ration Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂÃÂ©dÃÂÃÂ©ration Camerounaise de Football");
echo Encoding::fixUTF8("FÃÂ©dération Camerounaise de Football");

will output:

Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
Fédération Camerounaise de Football
