如何使这个rewrite规则支持中文啊？

现在使用如下的rewrite规则，中文出现乱码，如何使其支持中文啊？如果不需要支持中文，如果将字体去掉，直接rewirte数字得了，或者在数字的前面加上个字符：

RewriteRule ^([^/]*/)?[^/]+p[-_]?([0-9]+)\.html$ $1index.php?target=products&product_id=$2 [L]
RewriteRule ^([^/]*/)?[^/]+c[-_]?([0-9]+)([-_]sort[-_]([a-z0-9_]+)[-_]order[-_]([a-z0-9_]+))?([-_]page-([a-z0-9_]+))?\.html$ $1index.php?target=categories&category_id=$2&sort_by=$4&sort_order=$5&page=$7 [L]
RewriteRule ^([^/]*/)?[^/]+a[-_]?([0-9]+)\.html$ $1index.php?target=pages&page_inner_id=$2 [L]
RewriteRule ^([^/]*/)?[^/]+t[-_]?([0-9]+)\.html$ $1index.php?target=topics&topic_id=$2 [L]
RewriteRule ^([^/]*/)?[^/]+m[-_]?([0-9]+)\.html$ $1index.php?target=manufacturers&manufacturer_id=$2 [L]
RewriteRule ^([^/]*/)?form[-_]?([a-z0-9_]+)[-_]?(sent)?\.html$ $1index.php?target=forms&name=$2&mode=$3 [L]
RewriteRule ^([^/]*/)?manufacturers\.html$ $1index.php?target=manufacturers [L]
RewriteRule ^([^/]*/)?catalog\.html$ $1index.php?mode=catalog [L]
RewriteRule ^([^/]*/)?index\.html$ $1index.php [L]
