Charactor encoding support for Elixir. using ruster & "rust-encoding" crate. (Shift-JIS, EUC-JP, Big5.. other WHATWG encoding)
If available in Hex, the package can be installed
by adding mbcs_rs to your list of dependencies in mix.exs:
def deps do
[
{:mbcs_rs, "~> 0.1"}
]
endUsage:
iex> MbcsRs.encode!("日本語", "SJIS") |> MbcsRs.decode!("SJIS")
日本語
iex> MbcsRs.encode!("你好，世界", "BIG5") |> MbcsRs.decode!("BIG5")
"你好，世界"
iex> MbcsRs.encode!("한국어", "EUC-KR") |> MbcsRs.decode!("EUC-KR")
"한국어"
iex> File.stream!("KEN_ALL.CSV") \
|> Stream.map(&MbcsRs.decode!(&1,"SJIS")) \
|> Stream.filter(&String.contains?(&1,"福岡市中央区")) \
|> Enum.to_list
