encodeBin converts each character in a string to its binary representation, with each byte separated by spaces.
encodeBin takes no parameters.
str = "hello world"
log str.encodeBin()
// "1101000 1100101 1101100 1101100 1101111 100000 1110111 1101111 1110010 1101100 1100100"
// Each character is converted to its binary representation
str = "A"
log str.encodeBin()
// "1000001"
// Single character conversion
str = "🌟"
log str.encodeBin()
// Multiple bytes for Unicode characters
str = ""
log str.encodeBin()
// ""
// Empty string returns empty string
// Can be decoded back with decodeBin
encoded = "hello".encodeBin()
decoded = encoded.decodeBin()
log decoded
// "hello"
