Font tools written for one app each — Instagram, TikTok, Discord, WhatsApp, LinkedIn and the rest — covering what that platform actually allows in names, bios and posts.
Every platform treats text differently. Instagram accepts styled letters in the Name field but not the @username. LinkedIn has no formatting of its own, so Unicode is the only way to bold a post. Discord has real markdown and Unicode on top. Slack has formatting in messages but none in display names. Knowing the rule for your app matters more than knowing the alphabet.
Each page here documents the character limits, which fields accept styling and where search will stop matching your words, then offers styles that fit those rules.
Two fields, two different answers.
The cost of styled text is discoverability. Platform search, hashtags and mentions all match plain characters, so a fully styled bio becomes invisible to the people looking for it. The approach that works everywhere is one styled display line for personality and plain text for the words you want found. Each platform page shows where that line falls for that app.
Every generator here is built on the same four tools. Start with these if you want one place to convert, edit or browse characters.
On virtually no platform. Handles allow letters, digits and underscores. Style the display name instead.
Search matches plain characters. Styled letters are different code points.
Yes. They are characters, not formatting, so they render on every client.
Letters render everywhere. Only recent emoji can fall back to a box.
Yes.
