Q-3-55 — NoteDefinitionFencedBlock Not Supported in ANSI Format
Fenced note definitions cannot be rendered in ANSI terminal output.
What this means
A fenced note definition is the multi-paragraph form of a footnote — the body lives inside a fenced block attached to the note reference. The ANSI writer (used when rendering to a terminal) does not render footnotes at all, regardless of form.
Why this happens
Your document uses the fenced form of a note definition and you rendered to ANSI output.
How to fix
Render to a different format. HTML, PDF, and the markdown
writers all handle fenced footnotes. If the body is short
enough, you can also rewrite it as a one-line inline footnote
(text^[body]).
