Utf8 converter

To convert your input to UTF-8, this tool splits the input data into individual graphemes letters, numbers, emojis, and special Unicode symbols , then it extracts code points of all graphemes, and then turns them into UTF-8 byte values in the specified base. UTF-8 uses the following rules to encode the data.

If the code point value is less than , then it's the same value is used as the output byte value. If the code point is greater than , then it's turned into a sequence of two, three, or four bytes, where each byte of the sequence is between and You can easily switch between the four most popular bases for the UTF-8 bytes. Namely, you can choose to output UTF-8 as binary, octal, decimal, or hexadecimal numbers. If you need any other base, then you can select the "Custom Base" option and specify the required base value in the field below it.

This utility supports bases up to If you need to output UTF-8 in base, then use our Unicode to base converter. You can also adjust the delimiter that's used between the bytes in the output data. By default, it's the space character but you can set it to any other symbol. There are two more useful features that we have added. One of them lets you improve the appearance of bytes by padding short values with zeros to achieve a full byte length. Binary values get padded to eight bits, octal values to three symbols, and hex values to two symbols.

The other option lets you add a prefix in front of bytes. In binary, the prefix "0b" is added, in octal, the prefix "o" is added, and in hexadecimal, the prefix "0x" is added. Unicode to utf-8 converter examples Click to use. Napoleon Bonaparte's Quote. The quote is written in bold-italic Unicode letters and the output is UTF8 encoding of these letters.

It uses a space character between the octets and adds zeros in front of smaller bytes so that they are all 3 characters long. Required options These options will be used automatically if you select this example. Delimiter Set the byte delimiter character here. Add a Prefix Use prefix "0b" for binary, prefix "o" for octal, and prefix "0x" for hex values. Special Unicode Symbols. In this example, we convert four interesting Unicode characters to UTF8-encoded binary bytes.

We add a prefix "0b" in front of the binary values to make it unambiguous that the base is binary and pad some of them with zeros to achieve the length of 8 characters.

Bakery Emojis in Base In this example, we select a custom base from the output base dropdown and enter the value 21 in the custom base field. We then load a list of Unicode bakery products emoji as the input and UTF-8 encode them. We also use a dash symbol to separate base output bytes. Pro tips Master online unicode tools.

At Browserling we love to make developers' lives easier, so we created this collection of online UTF8 tools. Unlike many other tools, we made our tools free, without intrusive ads, and with the simplest possible user interface. Our online UTF8 tools are actually powered by our programming tools that we created over the last couple of years.

If the input form has weak UTF8 validation, then you may be able to bypass various security checks. Similarly, you can use an UTF8 encoder to find out what bytes are present in the input data.

For example, text can have homoglyphs that look like regular characters but are actually similar-looking Unicode characters. By encoding your data, you'll be able to tell what bytes each characters is made out of.

Additionally, you may use an UTF8 encoder to check how many bytes the input takes. If a browser checks data length, then by using weird Unicode characters, you can feed it more bytes than it expects that can lead to issues in your application. Looking for more web developer tools? Try these!
