The following packages should be installed before GNU Libidn2 is installed (runtime dependencies that are also build dependencies):

GNU libiconv
- Not needed on systems with glibc and on NetBSD. But recommended on all other systems. Needed for locale to UTF8 string conversions.
- Homepage: https://www.gnu.org/software/libiconv/

  - On Debian and Debian-based systems: --,
  - On Red Hat distributions: --.
  - Other: https://repology.org/project/libiconv/versions
- If it is installed in a nonstandard directory, pass the option --with-libiconv-prefix=DIR to 'configure'.
- On mingw, a slim alternative is the 'win-iconv' package version 0.0.8 from https://github.com/win-iconv/win-iconv .
