Language Switch without Trailing Slash for subdirectories

Hi,
the language switch is linking to the home url of subdirectories without trailing slash forcing an unnecessary redirect.
could you change

// link to siteurl of blog
get_site_url( $language_blog );

to

// link to siteurl of blog
get_site_url( $language_blog, '/' );
