Building my personal website

	Wide character in subroutine entry at /usr/share/perl5/IkiWiki/Plugin/search.pm line 222.

Causes a build failure. perl 5.40.1, utf-8 locale.

	return "U".lc(Digest::SHA::sha1_hex($page));

I suppose that it's $page that contains the wide character, and it
seems perhaps relevant that commit 4af7b2c14d548beaf09f100e7fc6efc39e9c73a2
already did some adjacent utf8 encoding of $page.

This will only affect wikis with long page lengths, 240+ characters.
