llvm dev - Oct 2020 - [RFC] Adding a char set converter to Support library

Hi!

On z/OS, there is the need to convert strings from EBCDIC to UTF-8 and 
vice versa.
Using the POSIX iconv functions has some challenges, so I created a small 
wrapper
around this functionality to get the same result on all platforms. This 
functionality
is required for reading and writing GOFF object files and can also be used 
in the
frontend.
I put up the code on Phabricator https://reviews.llvm.org/D88741. Please 
add your
comments to the review if you are interested in this topic.

Best regards,
Kai

As far as I remember, libiconv is under LGPL. Will this cause any troubles?

My understanding is that dynamically linking should pose no problem, but I 
am no lawyer. On Linux, glibc is also under LGPL license, and LLVM usually 
links against it.
(There is really no need for us to depend on libiconv. If it is deemed to 
risky, then I can dropped it.)
