In particular, opening and closing |

are represented as characters number 0x60 and 0x27, respectively, |

which agrees with all ASCII standards from 1965 to the latest |

revision (2012) and which matches the traditional way in which |

This correct ASCII rendering may look strange with modern |

Unicode-compatible fonts because contrary to ASCII, Unicode uses |

the code point U+0060 for the grave accent only, never for an opening |
