Pushed with this:

# Ensure programs with authors with non ASCII names link with LIBICONV
sc_check-I18N-AUTHORS:
       @(cd $(srcdir)/src &&                           \
         for i in $$(git grep -l -w proper_name_utf8 *.c|sed 's/\.c//'); do \
           grep -E "^src_$${i}_LDADD"' .?= .*\$$\(LIBICONV\)' local.mk > \
             /dev/null || { echo FAIL $$i; exit 1; };            \
         done)
