This fixes the original issue that I raised in #1322 (comment). However, I'm detecting one other failure in the Asciidoctor PDF test suite that is coming from changes in Prawn. I don't yet understand the failure. I'll report back once I do. |

Ha! The test is failing because Prawn is fixed. It was previously truncating Unicode characters outside of the 4-digit range (e.g., U+0f089a would become U+f089). Now the code does what it's supposed to do (preserves the original char code) and I just need to update the assumption in the test. False alarm. With that out of the way, I can confirm that this fix addressed the compatibility issues. |

Good to hear. Thank you. I will land this soon. |

Prawn correctly used width of missing glyphs to layout text but didn't encode the widths correctly in subset fonts. The resulted in characters with missing glyphs to have 0 width. And even though Prawn drawn Replacement Character glyphs they were stacking on top of each other because their widths were wrong.
