Re: master bf0aeaa0d7a: Re-enable displaying `han' characters on Android

[Eli Zaretskii <eliz@gnu.org>]

I've reverted the above commit.  The change which added those
characters was not an accident: I found that Emacs would choose an
inappropriate (sub-optimal) font for Chinese characters because it
generally stops looking once it find the first font that fulfills the
requirements.  The font Emacs sometimes selects due to those
characters missing lacked support for important Han blocks because
those blocks had no characters in script-representative-chars.

If this causes problems to Android, then please implement a fix that
is specific to Android, without affecting other platforms.

Thanks.

P.S. And once again, when you undo changes done by someone else just a
few days ago, please discuss this before making the change.
