Iconvex ICU Archive

Optional facade for the historical ICU mapping-table archive. Installing this package brings in all six version-locked data shards while keeping the large archive out of ordinary Iconvex feature packages.

def deps do
  [
    {:iconvex, "~> 0.1"},
    {:iconvex_icu_archive, "~> 0.1"}
  ]
end

The facade registers 1,050 source-qualified codecs. Its numbered, provider-only shards serve their mapping tables through the public Iconvex Core provider API. Canonical identities preserve the exact historical ICU source filename and revision, for example:

{:ok, utf8} =
  Iconvex.convert(
    bytes,
    "ICU-ARCHIVE-ibm-930_P120-1999",
    "UTF-8"
  )

Aliases are collision-reviewed across the frozen surface. Installing one ordinary feature package never pulls this archive; installing the facade explicitly brings in all six version-locked data shards.

For a sibling source checkout, set ICONVEX_PATH to the Core package and ICONVEX_ARCHIVE_PATH to the workspace directory containing this package and all six iconvex_icu_archive_data_XX directories. Published builds leave both variables unset and use Hex dependencies.
