How many random Unicode characters can I generate at once?

From 1 to 100 per press, returned as one continuous string. The default is 32. Press again for a fresh string; there is no history, so copy what you want to keep.

Why are some characters blank or shown as boxes?

The pool includes the first 6,000 code points of the Unicode table in full, which contains invisible control characters, spaces and a few unassigned positions, and your font may lack glyphs for some scripts. Boxes mean the character exists but the font cannot draw it; blanks are usually control characters or spaces.

Does the generator cover all of Unicode?

No. It draws from about 7,100 code points: U+0001 to U+1770, the Miscellaneous Symbols block, the main emoji range U+1F300 to U+1F64F, and five extra symbols. Chinese, Japanese and Korean ideographs, mathematical alphanumerics and newer emoji are outside the pool.

Can I use the output as a password?

You can, but many login forms reject or mangle non-ASCII characters, and typing 🐍ЖกΩ on a phone keyboard is slow. It is better suited to testing how a password field handles Unicode than to being the password.

Why does the string's length not match the number I entered?

Most tools count UTF-16 code units, and every emoji in the string uses two of them. The generator produces exactly the number of characters you asked for; counting by code point (for example with Array.from(str).length in JavaScript) gives the expected number.

Type a length from 1 to 100 (the default is 32), press the button, and you get a single string of that many random Unicode characters on a card with a copy button. A typical result mixes an emoji or two, a chess piece or weather symbol, and letters from scripts you may not recognize on sight: Cyrillic, Armenian, Devanagari, Thai, Ethiopic, Runic. It is built for people who need messy real-world text to throw at a form, a database column or a rendering engine, and for anyone who just wants a handful of unusual characters to copy.

Which characters can appear

Each character is picked independently from a pool of roughly 7,100 code points, made up of four blocks:

U+0001 to U+1770 (6,000 code points). The start of the Unicode table: ASCII letters, digits and punctuation, Latin-1 and Latin Extended accents, IPA, Greek, Cyrillic, Armenian, Hebrew, Arabic, Syriac, Thaana, the nine major Indic scripts from Devanagari to Malayalam, Sinhala, Thai, Lao, Tibetan, Myanmar, Georgian, Hangul Jamo, Ethiopic, Cherokee, Canadian Aboriginal syllabics, Ogham, Runic and the four Philippine scripts.
U+2600 to U+26FF (256). Miscellaneous Symbols: ☀ ☂ ☠ ☮ ♔ ♞ ♥ ⚒ ⚡ ⛄ ⛵.
U+1F300 to U+1F64F (848). The main emoji blocks, from 🌀 and 🌍 through 🍕, 🎉, 🐍 and 😀 to 🙏.
Five extras: ✓ ❤ 👍 😄 🚀.

Because the first block is a straight run of the table, it includes things you cannot see. The C0 and C1 control characters (U+0001 to U+001F and U+007F to U+009F), the space, and unassigned or combining code points are all possible picks. In practice that means a string will sometimes contain a blank, a box, or an accent mark that stacks onto the character before it. That is a feature if you are testing input handling and a nuisance if you wanted something purely decorative. Since characters are chosen independently, the same one can appear more than once in a string.

What a random Unicode string is good for

Input validation and storage tests. Paste a 100-character string into a username field, a search box or a database column defined as VARCHAR(50) and see what breaks. Byte-length limits, latin1 tables and naive sanitizers all show up fast.
Encoding round trips. Send the string through a JSON API, a CSV export, a URL parameter and a database and confirm it comes back identical. Mixed emoji and right-to-left Arabic or Hebrew are the usual trouble spots.
Font and rendering checks. Drop the string into a design mockup or a PDF generator to find scripts your chosen font does not cover; missing glyphs render as tofu boxes.
Length-counting demonstrations. A 32-character result may report a JavaScript .length of 40 or more, because each emoji occupies two UTF-16 code units. It is a quick, concrete way to show a team the difference between code points, code units and grapheme clusters.
Decorative or glitchy text. Usernames, art projects and "corrupted text" aesthetics. For something people can actually read, the Random Font Generator restyles ordinary words instead.

Code points, UTF-8 and why length is complicated

Unicode assigns every character a number called a code point, written U+ followed by hex digits: U+0041 is A, U+0416 is Ж, U+0E01 is ก, U+1F40D is 🐍. The current standard defines about 155,000 characters; this tool samples from a slice of them. How much space a character takes depends on the encoding. In UTF-8, the encoding used by nearly every web page and API, ASCII characters take 1 byte, most Latin, Greek, Cyrillic, Hebrew and Arabic letters take 2, Indic and Southeast Asian scripts and the Miscellaneous Symbols block take 3, and emoji take 4. A 32-character string from this generator can therefore be anywhere from 32 to 128 bytes, which is exactly the kind of thing a "max 64 characters" database column may or may not have been designed for.

If you only want pictographs, the Random Emoji Generator restricts itself to emoji, and the Random Symbol Generator covers typographic and mathematical symbols. For text art built from plain ASCII, see the ASCII Art Generator, and for the rest of the group browse all word and language generators.
