Decode hex string to character — hex_to

Converts a hexadecimal encoded string back into its original character representation. This is primarily used for reading human-readable data published to MultiChain streams.

Usage

hex_to_char(hex_str)

Arguments

hex_str: A character string in hexadecimal format.

Value

A decoded character string. If the input is not a valid hex string or an error occurs during decoding, the original hex_str is returned.

Details

The function performs a basic validation to ensure the string is a valid hexadecimal representation (even length and containing only hex characters) before attempting to convert.

Examples

hex_to_char("48656c6c6f")  # Returns "Hello"
#> [1] "Hello"
