For example, in the python file, the lengths of title lines and lines are inconsistent:
# before
# test text
# after
# ── test text ─────────────────────────────────────────────────
# ────────────────────────────────────────────────────────────
In the rust file, the lengths of the two are the same:
// before
// test text
// after
// ── test text ───────────────────────────────────────────────
// ────────────────────────────────────────────────────────────
