What to do

Characters

Paste the text as it is: no-break spaces and invisible characters are inspected too.

When a character is not what it looks like

Shows the Unicode code point (U+XXXX and decimal), UTF-8 bytes, HTML code and escape sequence for every character, turns codes back into characters, and flags no-break spaces, invisible characters and look-alike letters from another script.

A Unicode code is written as U+ and a hexadecimal number: é is U+00E9, decimal 233, two bytes C3 A9 in UTF-8 and é in HTML. The tool shows all of that for each character and works the other way too, turning a code in any notation into the character.

Two characters can look identical and still differ: Latin "o" is U+006F, Cyrillic "о" is U+043E. Swaps like that break search and string comparison. The breakdown flags letters from one script sitting among the other, no-break spaces, zero-width spaces, soft hyphens and the byte order mark.

How to use

Choose what to do: get the codes of characters, or get characters from codes.
Paste the text, or codes separated by spaces in any notation: U+00E9, \u00E9, \u{1F600}, é, é, 0xE9 or the decimal 233.
Read the breakdown: code, UTF-8 bytes, HTML code, and notes on invisible characters and look-alikes.

Notations for the same code

U+00E9 is the Unicode standard's notation, the code point in hexadecimal. é and é are HTML decimal and hexadecimal references. \u00E9 is the escape used in JavaScript, JSON and many programming languages; beyond U+FFFF, emoji for instance, JavaScript uses \u{1F600}.

Byte counts depend on the encoding. In UTF-8 one code point takes one to four bytes: the ASCII letter A takes 1, é or a Cyrillic letter 2, № or € 3, 😀 4; a compound visible character such as 👍🏽 takes more — eight here. In UTF-16 anything beyond U+FFFF takes two units, a surrogate pair, which is why a JavaScript string can be longer than the characters you see.

Invisible characters and look-alikes

These characters are invisible or indistinguishable from ordinary ones on screen, and the breakdown labels them with their official Unicode names. If a piece of text will not match a search, compare equal or work as a link, paste it here.

Names from the Unicode Consortium's UnicodeData.txt.
Code	Unicode name	What it is
U+00A0	NO-BREAK SPACE	a space that prevents a line break
U+202F	NARROW NO-BREAK SPACE	a narrow no-break space
U+200B	ZERO WIDTH SPACE	a space with no width
U+00AD	SOFT HYPHEN	a hyphen shown only at a line break
U+2060	WORD JOINER	an invisible joiner
U+FEFF	ZERO WIDTH NO-BREAK SPACE	the byte order mark (BOM)
U+200E	LEFT-TO-RIGHT MARK	a text direction mark
U+2212	MINUS SIGN	a minus sign, not the hyphen U+002D

What this calculator shows

Each character's code: U+XXXX and decimal
UTF-8 bytes, HTML code and escape sequence
Characters from codes written as U+, \u, &#, &#x or 0x
Labels on invisible characters and letters from another script
Code points, UTF-16 units and UTF-8 bytes for the whole string

What to keep in mind

Only the first 40 characters or codes are inspected: the tool is for checking individual characters rather than whole documents.
Names appear only for the invisible and confusable characters in the table above; everything else gets its code and bytes.

FAQs

How do I find a character's code?

Paste the character into the tool: it shows the code as U+XXXX, the decimal number, the UTF-8 bytes and the HTML reference &#…;.

How do I get a character from its Unicode code?

Choose "Get characters from codes" and enter the code in any notation: U+2116, \u2116, №, № or 8470 all give №.

What is the code for a no-break space?

U+00A0, decimal 160,   or   in HTML, bytes C2 A0 in UTF-8. It looks exactly like an ordinary space, U+0020, but stops the line breaking there.

How many bytes does a character take?

One to four in UTF-8: a Latin letter 1 byte, é or a Cyrillic letter 2, symbols such as № and € 3, an emoji 4. The tool shows the bytes for each character and the total for the string.

What is the difference between a code point and a UTF-16 unit?

Characters beyond U+FFFF, including most emoji, take two UTF-16 units. That is why a string's length in JavaScript can exceed the number of characters you see.

How do I spot a Latin letter hiding among Cyrillic ones?

Paste the word and look at the codes: a Cyrillic о is U+043E, a Latin o is U+006F, and they look identical on screen. The tool flags Latin look-alikes mixed into Cyrillic text.

Worked example

A café with a no-break space

Input: é № and a no-break space before café

Output: U+00A0 — no-break space (NO-BREAK SPACE)

Note: On screen it looks like an ordinary space, but a search for the phrase typed with a normal space will not find it.
