Titles and Shorts
YouTube titles do not accept *asterisk* bold. Unicode glyphs stay bold in search, suggested videos, and Shorts.
Descriptions and posts
Use bold section labels like Timestamps, Gear, or Sponsors. Same trick works in community posts and pinned comments.
Use it sparingly
One or two bold words beat a fully bold title. Keep the searchable keyword in normal letters at least once.
Where this works, and what to watch for
Paste the output into video titles, Shorts titles, playlist titles, channel names, the About tab, descriptions, comments, and community posts.
Screen readers may announce these as mathematical bold letters. Keep critical information in plain text if accessibility matters for your audience.
Search may treat Unicode bold as different characters, so leave the main keyword in normal text somewhere nearby. Mathematical bold can also count as two YouTube units per letter.
