Marking as ready for test.

The attached patch adds support for ND character arrays.
Also I don't know whether it is always true that upper-case and corresponding lower-case characters (and vice-versa) are represented with the same number of bytes. So I added a fallback for this case.

It passes all tests on Linux (Ubuntu 18.04) and Windows 10 (1803) for me.

I filed a new bug report about the issue with non-ASCII characters in the test suite on Windows in bug #53875.

The attached patch uses gnulib's u8_tolower and u8_toupper instead of the corresponding functions from the standard library.

The tests will fail on Windows because the .tst-files will be read with the system code page but all our sources are in UTF-8.
We could fix this by temporary switching to UTF-8 while running the test suite. I'll open a new bug report about this.

We should wait with applying this patch until the other bug will be fixed.
