Bubble text generator

Five kinds of bubble letters

Bubble text is not a font. Each bubble letter is a single Unicode character with the circle or square built in, like Ⓑ (U+24B7). That is why it pastes as text into a bio, a name or a chat, where you can't pick a font.

Unicode has five sets of these letters, and none of them is complete. Only the white circles have both capitals and small letters.

The older white circles and brackets came from East Asian character sets, where circled numbers mark lists. The black circles and the squares came later, in 2009 and 2010. Some were first needed for Japanese TV and phone symbols, and Unicode then filled in the rest of the alphabet. If you mean the big, puffy bubble letters people draw on posters, those are drawn over several lines. Make them with big text art.

Circled numbers from 0 to 50

Most bubble generators put 12 in two circles, ①②. Unicode also has whole numbers in one circle, up to ㊿. The generator uses them when "Numbers up to 50 in one bubble" is on. There is no circled 51, so bigger numbers go digit by digit.

What happens to characters with no bubble?

The generator never drops a character. When a style has no bubble for it, one of three things happens:

• A small letter in black bubbles or squares becomes a capital, because those styles have no small letters. In brackets it goes the other way: capitals become small letters.
• A letter with an accent, like é, gets a plain bubble. Unicode has no bubble with an accent, so the accent comes off.
• Everything else stays as it is: punctuation, emoji, letters from other alphabets, and numbers in the square styles.

Each card marks these characters and lists them in the line under it. A few math signs have a circled form of their own. Tap one to copy it:

⊕ ⊖ ⊗ ⊘ ⊙ ⊛ ⊜

To put any character in a circle, there is a combining circle mark, U+20DD, that draws around the character before it, like a⃝. It lines up badly in most fonts. The character wrapper has it, along with brackets that work around every letter.

Bubble letters that turn into emoji

Some bubble letters are also emoji. 🅰 🅱 🅾 🅿 are the blood type and parking signs, and Ⓜ is the sign for a metro station. Unicode lets them show as plain letters or as colored emoji, and some phones pick the emoji. Your black square text can then have red A, B, O and P in the middle.

They became emoji with Unicode 6.0 in 2010. The same version added whole words in squares, and these always show as emoji. Tap one to copy it:

🆒 🆓 🆕 🆗 🆙 🆘 🆚 🆔 🆑 🆖 🆎

The Wikipedia article on the Enclosed Alphanumeric Supplement lists every letter and sign in this Unicode block.

Speech bubbles and frames in plain text

The speech bubbles, frames and faces are made of normal characters, so they paste anywhere text goes. The boxes use line drawing characters like ╭ and ─, and the animals use plain ASCII signs like / and _.

Art with more than one line keeps its shape only in a monospace font, where every character is as wide as the next. Notepad, code and Discord code blocks use one. A chat or a social post uses a normal font, so the right side of a box can drift. The one line faces and bubble lines look right in any font.

Emoji and Chinese or Japanese letters take two columns in most monospace fonts, and the cards count them that way. Some fonts draw them a little wider, so a box around emoji may not close exactly.

Bubble text and character limits

Many apps count text in code units, the way JavaScript stores it. White circles and brackets are in the first 65,536 characters of Unicode and count as one each. Black circles and both kinds of squares are higher up and count as two, so a short bubble name can hit a limit sooner than you think.

Screen readers have a harder time. They read each bubble by its Unicode name, like "circled latin capital letter B", or skip it. Use bubbles for a short name or a heading, and keep the rest in plain letters.
