The packed mapping tables, aliases, transliteration data, conformance fixtures,
and state-machine behavior are derived from GNU libiconv. GNU libiconv and this
derived work are licensed under the GNU Lesser General Public License, version

The directory test/fixtures/gnu-libiconv-1.19 is a
267-file byte-exact upstream mirror plus one derived configured Makefile.
Their complete 268-file aggregate
content digest is:
546c5b74a57687415f6bc67548dc1a190e9be54417b4df530addf7f9b96b095d

That repository-only mirror includes tests/uniq-u.c, which is GPL-3.0-only. Its
corresponding repository-only license text is LICENSE.GPL-3.0. Both files are
excluded from the Hex artifact; the GPL test utility is never compiled, linked,
or used by the Iconvex runtime.

The runtime implementation is native Elixir/BEAM code and does not link to or
execute GNU libiconv.

The directory test/fixtures/gnu-libiconv-1.19-encodings contains byte-exact
copies of GNU libiconv 1.19's seven encoding definition files plus output from
the verified default-build `iconv -l`. Its aggregate content digest is:

test/fixtures/all-unicode-codepoints.ucs4be is generated data containing every
Unicode code point from U+0000 through U+10FFFF in ascending UCS-4BE order. Its
1,114,112 entries include the 1,112,064 Unicode scalar values and all 2,048
surrogate code points, which are not scalar values. It has 4,456,448 bytes and
