[dev] Horde_Util Transliterate iconv test

[Ralf Lang]

Hi,

we detected a problem with the horde_util iconv test (at least our
version) - some conversions are not happening as expected.

Here's our test suite by Marco (with the affected tests skipped for now).

I tried to look into horde's original test suite but I did not find any
differences.

Then I wanted to check if the original tests also fail in travis-ci.

This run also has some skipped tests but I think this version works.

I don't have a very deep understanding of iconv. I also see very
different kinds of garbage depending on which editor I actually use.

Would it be OK to change the raw UTF-8 chars in the test fixtures into
\x or \u representation (with comment) or something similar?
