[Mediawiki-l] StripforSearch in LanguageUtf-8 and LanguageZh*

[kent sin]

I am trying to understand the language related coding for Chinese: I
have find that

the StripForSearch defined in utf8 and zh* were like this:

$out = preg_replace(
			"/([\\xc0-\\xff][\\x80-\\xbf]*)/e",
			"'U8' . bin2hex( strtr( \"\$1\", \$wikiSearchChars ) )",
			$string );

My question is :

Why the strtr is place in here but not

$out = preg_replace(
			"/([\\xc0-\\xff][\\x80-\\xbf]*)/e",
			"'U8' . bin2hex(  \"\$1\" )",
			strtr( $string, $wikiSearchChars ) );
