ctest update.

* some Japanese (platex) documents fail with inputenc "utf8-platex"
  (missing characters in non-Japanese text parts), because the
  Unicodechar definitions from "inputenc" are not used.

* some Japanes (platex) documents show wrong output with "auto",
  because platex ignores the encoding switch for text parts
  in other languages.

* Japanese Beamer documents must set default output to "pdf",
  because dvipdfm(x) produces wrong output with document class "Beamer".

* update tagging/inverting rules.

* use HE8 font encoding for Hebrew in language test.
