Frequently asked questions
Can I bold text in a Mastodon toot?
Mastodon's composer is plain text with no bold button, so the formatter substitutes Unicode bold characters that show up styled across instances.
Will Unicode formatting federate correctly?
Yes. Because it is plain Unicode rather than markup, styled text appears the same on whatever instance or app receives the federated post.
