Description

Zend_Filter_StringTrim uses trim(), so there are two problems. - It does not filter the characters like U+0085 next line and U+00A0 no-break space. -- You can use preg_match('/^[\s\p{Zs}\p{Zl}\p{Zp}]+$/u', $str) to see what characters are white spaces in UTF-8. - If the trim_charlist parameter includes multibyte characters, it does not work as expected. -- The returned string is cut in the middle of the multibyte character.

$trim_charlist = " \t\n\r\0\x0B・。"; $filter = new Zend_Filter(); $filter->addFilter(new Zend_Filter_StringTrim($trim_charlist)); $s = $filter->filter($value);

There is neither mb_trim() function or iconv_trim function in php core. We need to trim with preg_replace or something. @see http://bugs.php.net/bug.php?id=23501 http://php.oregonstate.edu/manual/en/…
