The current version of t5enc.def (as in the TeXLive repository) gives

  \'i  -> í
  \'\i -> í
  \`i  -> ì
  \`\i -> ì
  \~i  -> ĩ
  \~\i -> ĩ
  \h i -> ỉ
  \h\i -> ỉ
  \d i -> ị
  \d\i -> ị             (*)

I consider the entry marked with (*) as an error and will probably
remove it in an upcoming revision.

The difference between T5 and the other T encodings regarding \~i is
justified IMHO.  I'm even going to say that the behaviour in the
non-T5 encodings is incorrect; they miss entries like


which aren't there because `ĩ' is not used in any other language
besides Vietnamese AFAIK, so there was never a need to add them.
