Environment variable GHC_CHARENC lacks documentation
Location of documentation issue: https://ghc.gitlab.haskell.org/ghc/doc/users_guide/using.html#other-environment-variables
GHC_CHARENC
is undocumented.
GHC_CHARENC
is used e.g. here: https://github.com/ghc/ghc/blob/0dc723957d0fdb5909f145405b775efea0fe2f6e/libraries/ghc-boot/GHC/HandleEncoding.hs#L9-L17
Blame goes to https://github.com/ghc/ghc/commit/1b56c40578374a15b4a2593895710c68b0e2a717
Context: https://github.com/agda/agda/issues/5742
Btw: GHC_CHARENC
does not follow any identifier standard I am aware of. (As opposed to GHC_CHAR_ENC
or GHC_CHAR_ENCODING
.) [Also, my subconscious produces misspellings such as GHC_CHARENV
and GHC_CODEENV
.]
