utf8ToBytes

The utf8ToBytes function is a utility method provided by the web3.utils module that converts a string to a Uint8Array.

The function takes a string argument, denoted by the str parameter. The function returns a Uint8Array that represents the binary representation of the string.

The conversion is performed by iterating over each character in the string and converting it to its corresponding UTF-8 byte sequence. The resulting Uint8Array will have a length equal to the number of characters in the string.

Here's an example of how the utf8ToBytes function can be used:

In this example, the utf8ToBytes function is called with a string argument, and it returns a Uint8Array that represents the binary representation of the string.
