Try the latest beta and let me know if this helps.
But let me also make a few clarifications, to try to eliminate some possible confusion:
- The Markdown parser used for title fields is not a full Markdown parser, but something that has been intentionally simplified to handle specific issues that may legitimately arise in titles;
- I believe the issues raised in this post are all related to the simplified parser used for the title field, not for the full-blown parser used on the body field;
- I’ve added some code to the simplified parser so that underlines embedded within words should now be left as underlines.
Let me know if this change does not sufficiently address the issue.
Thanks for the question!
