GHC.Internal.Encoding.UTF8

The API of this module is unstable and not meant to be consumed by the general public. If you absolutely must depend on it, make sure to use a tight upper bound, e.g., base < 4.X rather than base < 5, because the interface can change rapidly without much warning.

Simple UTF-8 codecs supporting non-streaming encoding/decoding. For encoding where codepoints may be broken across buffers, see GHC.IO.Encoding.UTF8.

This is one of several UTF-8 implementations provided by GHC; see Note [GHC's many UTF-8 implementations] in GHC.Encoding.UTF8 for an overview.
