[Koha] Wide character error

Hello all, We have an error appears during navigation through ( patron pages) in koha 16.11 for example when trying to enter a patron details page from koha staff client like ( http://domain_name:8080/cgi-bin/koha/members/moremember.pl?borrowernumber=29...) page, It gives us this error ( Wide character in subroutine entry at /usr/share/perl5/Digest/HMAC.pm line 63.) Also, The same error appears when trying to open OPAC (http://domain_name/cgi-bin/koha/opac-memberentry.pl) page. Thanks in advance Regards.
