 Hi,

 I noticed that the `get_theme_mod` function use sprintf on the `$default`
 parameter, as seen on this line:
 https://core.trac.wordpress.org/browser/tags/4.9.5/src/wp-
 includes/theme.php#L872

 Any `%` character in the `$default` string would be stripped.

 For example:
 `get_theme_mod( 'my_theme_mod_key', '100%' );` would return `'100'` as the
 default value, not `'100%'`.
