/// This is the legacy Unix encoding for Japanese.
///
/// For compatibility with Web servers that don't expect three-byte sequences
/// in form submissions, the encoder doesn't generate three-byte sequences.
/// That is, the JIS X 0212 support is decode-only.

/// [Index visualization](https://encoding.spec.whatwg.org/euc-jp.html),

/// This encoding roughly matches the Windows code page 20932. There are error
/// handling differences and a handful of 2-byte sequences that decode differently.
/// Additionall, Windows doesn't support 3-byte sequences.
