I have the following address line: Praha 5, Staré Město,
I need to use utf8_decode() function on this string before I can write it to a PDF file (using domPDF lib).
However, the php utf8 decode function for the above address line appears incorrect (or rather, incomplete).
The following code:
<?php echo utf8_decode('Praha 5, Staré Město,'); ?>
Produces this:
Praha 5, Staré M?sto,
Any idea why ě is not getting decoded?
utf8_decode converts the string from a UTF-8 encoding to ISO-8859-1, a.k.a. "Latin-1".
The Latin-1 encoding cannot represent the letter "ě". It's that simple.
"Decode" is a total misnomer, it does the same as iconv('UTF-8', 'ISO-8859-1', $string).
utf8_decode converts the string from a UTF-8 encoding to ISO-8859-1 This saved me probably couple of hours! would gladly buy you a drink if you were in our office :)I wound up using a home-grown UTF-8 / UTF-16 decoding function (convert to &#number; representations), I haven't found any pattern to why UTF-8 isn't detected, I suspect it's because the "encoded-as" sequence isn't always exactly in the same position in the string returned. You might do some additional checking on that.
Three-character UTF-8 indicator: $startutf8 = chr(0xEF).chr(187).chr(191); (if you see this ANYWHERE, not just first three characters, the string is UTF-8 encoded)
Decode according to UTF-8 rules; this replaced an earlier version which chugged through byte by byte:using
function charset_decode_utf_8 ($string) {
/* Only do the slow convert if there are 8-bit characters */
/* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */
if (! ereg("[\200-\237]", $string) and ! ereg("[\241-\377]", $string))
return $string;
// decode three byte unicode characters
$string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])/e",
"'&#'.((ord('\\1')-224)*4096 + (ord('\\2')-128)*64 + (ord('\\3')-128)).';'",
$string);
// decode two byte unicode characters
$string = preg_replace("/([\300-\337])([\200-\277])/e",
"'&#'.((ord('\\1')-192)*64+(ord('\\2')-128)).';'",
$string);
return $string;
}
Problem is in your PHP file encoding , save your file in UTF-8 encoding , then even no need to use utf8_decode , if you get these data 'Praha 5, Staré Město,' from database , better change it charset to UTF-8
you don't need that (@Rajeev :this string is automatically detected as utf-8 encoded :
echo mb_detect_encoding('Praha 5, Staré Město,');
will always return UTF-8.).
