The character set used for the markdown output is ASCII. |

Non-ASCII characters are encoded as HTML entities. |

Since that is not possible in literal font contexts, because these |

non-ASCII characters are transliterated to ASCII approximations in |

these contexts. |

Markdown is a very weak markup language, so all semantic markup is |
