Seems to parse & generate description of http://minikanren.org/ alright, but crashes when rendering response.

Request: POST /api/page/fetch

The offending bit of text is "mímirKanren". It seems like going through Floki's parsing/processing turns strings into byte-lists at some point, and this results in Elixir no longer seeing the binary list as a valid string (because what should be a single code point > 255 got split into multiple bytes).
