Spacing

Case

Spacing options double your character count. On a 150-character bio that matters.

What do the labels on each card mean?

U+1D400 The Unicode codepoint the style's characters come from. Two styles can look almost identical and still be different characters with different device support. The codepoint is the only reliable way to tell which one you copied.

Not on Roblox Only the exceptions are listed. A card showing nothing here works on all seven platforms in the fields that accept styled text. Partly on means it works but breaks on some devices or in some fields. Not on means that platform filters or rejects it.

No platform accepts styled text in a username. That is the field, not the style.

Or jump to every style, symbols or the bio builder.

Why this one

Nothing is typed by hand

Every style and symbol is generated from the Unicode database and checked as it is built. No unassigned characters, no near-duplicates, and no circled "1" that turns up as a "2". Each card shows its codepoint so you can look it up yourself.

We say when it does not work

Instagram rejects styled usernames. Roblox strips them from chat. Half the styles here have no digits at all. All of that is on the pages, because a tool that only tells you the good news is no help when your bio arrives broken.

Sourced, or said to be uncertain

Platform limits come from each platform's own documentation where it exists. Where sources disagree, the page says so rather than picking one and hoping. How we check facts.

Everything else

Bio builder Build a bio for any platform, counted against the right character limit, with a warning when a style will not survive the field. Font styles Every style, with a live preview of each rendered in itself and the Unicode block it comes from. Symbols Hearts, stars, arrows, brackets and dividers. Every character verified against the Unicode database. Bio examples Six worked examples with the reasoning behind every line. Which stay plain, which get styled, and why. By platform What Instagram, TikTok, Discord, WhatsApp, X and Roblox each accept, and which field to paste into. Gaming names Name limits and rename costs for Free Fire, BGMI, PUBG and Roblox. Compose it before you spend the card. Guides Why styled text shows as boxes, what a screen reader hears, and where these characters came from.
