  Log where a cursor position lands when mapped into article text

  Ghost released this 2026-07-27 00:42:29 +03:00 | 1807 commits to dev since this release

  Pressing Enter with the cursor right after an emoji moves the emoji
  down with the tail, instead of leaving it on the line above. The split
  lands one emoji to the left of the cursor.

  richOffsetForFieldOffset() converts the field cursor into an offset in
  the article text through a list of replacements, and that list is only
  ever filled from formulas — see MarkedTextLeafSourceSignature's caller
  in iv_editor_text_entities.cpp. An emoji changes length between the two
  coordinate systems exactly the same way a formula does: one character in
  the field document, two UTF-16 units in the text. Nothing compensates
  for it.

  The direction fits, the magnitude does not yet: four emoji precede the
  cursor in the reported case, so the shortfall should be four units, but
  the split moved by two. Rather than guess again, log both offsets, the
  text length, the replacement count and what sits on either side of the
  landing point.

  Temporary diagnostics, capped at 60 lines per run.
