The conversion tables for KSC5601 are old, because of my mistake.
I made new tables and put them into
ftp://ftp.netbsd.org/pub/NetBSD/misc/tshiozak/misc/ksc/

how to install them:
  zcat KSC5601%UCS.src.bz2 | mkcsmapper > KSC5601%UCS.mps
  zcat UCS%KSC5601.src.bz2 | mkcsmapper > UCS%KSC5601.mps
  sudo install -c -m 0444 KSC5601%UCS.mps UCS%KSC5601.mps \
      /usr/share/i18n/csmapper/KS/
  

Because the master repository of NetBSD is now migrating,
I will commit them later.

It is better to fix the program as:

-	utf8_strlen = strlen(utf8_str);
+	utf8_strlen = strlen(utf8_str)+1;

or

-	printf("%s\n", euckr_str);
+	printf("%.*s\n", (int)(sizeof(euckr_str) - euckr_strlen), euckr_str);
