[Bytes] creates a byte stream that can be used to work with binary data or to convert strings from one character set to another. The [Bytes] tag can be used to instantiate a new bytes object, or it can be used to cast string data types as bytes types. Only string data types may be cast as bytes data types.

In the first form the tag accepts two optional parameters. The first parameter is a string to be imported into the byte stream. The second parameter defines what character set the string is transformed into before it is imported (e.g. iso-8859-1). If no character set is specified then the string is imported as UTF-8.

In the second form the tag accepts two optional parameters. The first specifies the size of the memory buffer in bytes that should be allocated to hold the byte stream. The second specifies the number of bytes that should be added if the initial memory buffer is too small to hold the entire byte stream.

[Var: 'Bytes_Growth' = (Bytes: 1024, 256)]
Optional Parameters

Grow Size The increment in bytes to grow the byte stream buffer.
