 When you change `$pagination_base`/`$comments_pagination_base` for
 `WP_Rewrite` instance to string with ASCII characters, it works as
 expected. But when you change to non-ASCII string, it doesn't work because
 it redirects from `/<pagination_base>/2` to
 `/<pagination_base>/2/<pagination_base>/2` which returns 404.  If you use
 `rawurlencode()` on that string, it again works as expected.

 So, in short:
 `$GLOBALS['wp_rewrite']->pagination_base = 'something';` - works
 `$GLOBALS['wp_rewrite']->pagination_base = 'чџш';` - doesn't work
 `$GLOBALS['wp_rewrite']->pagination_base = rawurlencode( 'чџш' );` - works

 This doesn't apply to other bases, they work without `rawurlencode()`, for
 example:
 `$GLOBALS['wp_rewrite']->author_base = 'гдђ';`
