Given that there is no single byte tilde in shift_jis then shouldn't "//TRANSLIT" give the ascii code all the same? //TRANSLIT seems to break at the tilde and not display either the ascii code or the rest of the string. For some unknown reason shift-jis encoded pages seem to display the char(126) 7E character as a tilde and not an overbar, so the fact that the tilde does not exist would not be a problem if it were TRANSLITted. http://md2.cc.yamaguchi-u.ac.jp/~eigo/temp/tilde.php Previous Comments: ------------------------------------------------------------------------ [2008-05-16 07:16:52] nospam at nihonbunka dot com Hmm tilde is often displayed and used in Japan. How can this be? I have web pages such as that below, which I can type into and display on a shift_jis encoded page http://md2.cc.yamaguchi-u.ac.jp/~eigo/temp/tilde.php The contents of this file is <?PHP $string = 'https://md2.cc.yamaguchi-u.ac.jp/~eigo/temp/tilde.php'; // This is what we start off with echo ('this is what we start with = '.$string.'<BR />'); //print string at start $conv_str = iconv('utf-8','shift-jis'.'//TRANSLIT',$string); echo ('this is not working = '.$conv_str.'<BR />'); //Just to show that this is not working. $rstring = preg_replace ('/~/','1bytetilde',$string); //modify before conversion echo ('this is modified string here = '.$rstring.'<BR />'); //This is the modified string $conv_str2 = iconv('utf-8','shift-jis'.'//TRANSLIT',$rstring); //convert $rereplace=chr(126); //$rereplace is a one byte tilde in shift_jis $rerstring = preg_replace ('/1bytetilde/',$rereplace,$conv_str2); //rereplace with tildes echo ('this is the correct result = '.$rerstring.'<BR />'); //the correct result ?> ------------------------------------------------------------------------ [2008-05-16 06:12:33] [EMAIL PROTECTED] That's because shift-jis doesn't support the (ASCII) tilde. (Unicode char 0x7D): http://demo.icu-project.org/icu-bin/convexp?conv=ibm-943_P130-1999&ShowSet&s=ALL#ShowSet ------------------------------------------------------------------------ [2008-05-16 02:11:51] nospam at nihonbunka dot com Description: ------------ inconv does not seem to convert single space tildes from utf8 to shift_jis Please bear in mind that shift_jis tildes are not where one would expect them to be. http://en.wikipedia.org/wiki/Shift-JIS "The single-byte characters 0x00 to 0x7F match the ASCII encoding, except for a yen sign at 0x5C and an overline at 0x7E in place of the ASCII character set's backslash and tilde respectively." If I use //IGNORE then the tildes just disappear. If I use //TRANSLIT the bug is even worse - all of the string after and including the first the ~ disappears. There was also a double byte tilde problem in the past, but this is different. Reproduce code: --------------- <?PHP $conv_str = iconv('utf-8','shift-jis'.'//IGNORE','where are the (~) (~) tildes?'); echo ($conv_str); ?> Expected result: ---------------- where are the (~) (~) tildes? the above in shift_jist using //IGNORE Actual result: -------------- where are the () () tildes? using //IGNORE and where are the ( using //TRANSLIT ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=45017&edit=1
