+With the switch of Anthy's upstream to Debian, Anthy switched to
+utf-8 backend. However, it still supports EUC-JP encoding.
+Anthy-utf8 backend needs to be used, though.

+Quote from: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=953616

+> If you have customized enabled-im-list on "stretch" system (in
+> ~/.uim.d/customs/custom-global.scm) with uim-pref-gtk or other tools,
+> uim sticks to use anthy instead of anthy-utf8 and fails kanji-conversion.

+If you have said customization, please remove them.
