Bold, italic, bold italic, bold sans, script, small caps and fullwidth: the styles that render on X's timeline, pinned at the top.

Text formatting on X is limited to a few premium features, and none of them reach the display name or the bio. What has always worked is Unicode: ๐๐จ๐ฅ๐, ๐๐ก๐๐๐๐ and ๊ฑแดแดสส แดแดแด๊ฑ are characters, not formatting, so they show in a tweet, a reply, a name, a bio and a quote-tweet alike, on every client.
The seven styles pinned here are the ones X's web and mobile apps render cleanly and that stay legible at timeline size: bold, italic, bold italic, bold sans, script, small caps and fullwidth. Combining-mark styles (strikethrough, zalgo) also post, but X's line height clips the stacked marks in names.
One caution before you post: X's search does not match styled letters to plain ones, so keep hashtags and the words you want found in plain text.

Bold serif is the classic; bold sans matches X's own interface font more closely. One bold phrase in a plain tweet reads as emphasis.

Script is the decorative choice; small caps stays readable at the timeline's 15px name size.
Type it here, copy the Bold card, and paste it into the tweet. The bold letters are Unicode characters (๐๐จ๐ฅ๐), so they post on any account and show on every client.
Yes, and most of them count double: X measures the styled letters as two characters each, so a bold tweet holds roughly half as many letters as a plain one.
In the display name, yes. The @handle accepts only letters, digits and underscores.
No. Styled letters are different characters from plain ones, so a search for the plain word will not match. Keep hashtags and searchable words plain.
