String Literal Creator

World's Simplest Unicode Tool

This browser-based utility converts Unicode text to a string literal. Anything that you paste or enter in the text area on the left automatically gets converted to a string literal on the right. It supports the most popular Unicode encodings (such as UTF-8, UTF-16, UCS-2, UTF-32, and UCS-4) and it works with emoji characters. You can use code points or bytes in the literal sequences as well as customize their format. You can also change the literal delimiter and create a proper string by wrapping it in double quotes. Created by encoding gurus from team Browserling.

Convert escape codes to uppercase.
Wrap output in double quote marks.

Code Point Format

Choose format for code points.
Set a custom code point format here.
Valid formats are %B – binary, %O – octal, %D – decimal, %H – hex, %U – surrogate pair. Use \B, \O, \D, \H, \U to write literal letters B, O, D, H, U.

Byte Format

What Is a String Literal Creator?

This utility converts Unicode glyphs to literal strings that you can use in various programming languages and configuration files. It takes the input Unicode data, converts it to binary bytes and code positions, and outputs them as a sequence of escape codes. You can use eight different formats for code positions, such as Java escape codes (\uHHHH), Ruby escape codes (\u{HHHH}), HTML, XML, and XHTML escape codes (&#D; and &#xHH;), and others. If none of these formats are suitable for you, you can define your own format. To do this, select the "custom" code point format and enter your own format. To print binary code positions, use %B notation, octal code positions – %O, decimal – %D, hexadecimal – %H, or hexadecimal surrogate pairs – %U. To write ordinary letters B, O, D, H, U, add a backslash in front of them. For example, \B will write B and \\ will write a slash. There are sixteen different formats for working with bytes, including Perl escape codes (\x{HH}), SQL escape codes (#HH#), and C escape codes (\xHH). You can also set a custom escape format for bytes using the same notation as for code points (except %U). Additionally, for byte escape codes, you can choose the Unicode encoding of your data. We support UTF-8 (default), UCS-2, UTF-16-LE, UTF-16-BE, UCS-4, UTF-32-LE, and UTF32-BE encodings and optionally you can add a Byte Order Mark (BOM). You can also print escape codes in uppercase and change the delimiter that gets placed between escape codes. To make the string literal immediately usable, you can also wrap the output in double quotation marks.

Java String Literal

In this example, we convert a quote from Albert Einstein to a Java string literal. We use the u-prefix format, which converts each Unicode character to a hexadecimal code point pair and adds the prefix \u in front. We wrap the string literal in double quotes and you can paste it directly in your JavaScript code and it will work.

Unicode Snail

This example encodes snail art created from various Unicode characters to a literal hex string. It applies UTF8 curly-hex-byte format used in Perl code to every character. This format puts hex bytes in curly brackets and adds a backslash and the hex prefix "x" before each byte. The bytes are printed in uppercase and they are separated by the space symbol.

Medical Emojis

In this example, we create our own custom string literal using a custom byte format. We select the "custom" format from the byte format list and enter the format value "#$%H". The first two characters "#$" are the escape prefix and the last two "%H" correspond to a non-padded hexadecimal byte value. We set the escape code separator symbol to a comma to clearly show each byte and wrap the entire sequence in quotes. The input medicine emoticons are encoded as UTF-16 Little Endian bytes with a BOM indicator (the first two bytes).
