Haddock to Latex fails on Data-Text-Internal

[pjljvandelaar]

When I run
stack haddock --haddock-arguments "--latex"
on a project that contains Data.Text (from text 1.2.3.0), I get

    haddock: internal error: .stack-work\dist\67675594\doc\html\text\Data-Text-Internal.tex: commitBuffer: invalid argument (invalid character)

After which haddock stops.

Could this offending character be removed?

Of course, maybe the bug is in haddock: see haskell/haddock#929.

I couldn't reproduce this with

cabal new-haddock -w ghc-8.4.3 --haddock-options=--latex

I've looked at the haddock code-base and it looks like this is a haddock bug that occurs for the corner case of using --latex in combination with an inappropriate system locale.

I'm closing this in favor of handling this upstream at haskell/haddock#929
