In PHP 5 must be UTF-8 encoded. The truth is that this value do not have to be encoded in UTF-8. The encoding of this string depends on the setting of idn.default_charset This setting by default is set to ISO-8891-1 and therefore a string containing a utf8-encoded character that's invalid in ISO-8891-1 will cause the parser to crash (ending up in an "segmentation fault" message). Try the test-script once with the ini-value idn.default_charset of "ISO-8891-1" and once of "utf-8". Using the default-value (iso-8891-1) the script will break and using "utf-8" instead it will work as expected. Test script: --------------- <?php var_dump( idn_to_ascii('ә') ); echo "123"; Expected result: ---------------- PHP Notice: IDN_IDNA_TO_ASCII: Could not convert from IDNA to ASCII in /var/www/index.php on line 1 123 Actual result: -------------- PHP Notice: IDN_IDNA_TO_ASCII: Could not convert from IDNA to ASCII in /var/www/index.php on line 1 Segmentation fault ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=60647&edit=1
