Convert String to Byte

Question

Hi

I need to convert a Char to an Byte. I belief this should be very simple but i don't find a nice solution.

0x7A.toChar => 'z'
'z'.???? => 0x7A

Edit:

I'm to tired... 'z'.toByte => 0x7A

Answer 1

scala> 'z'.toByte
res0: Byte = 122

scala> res0.toChar
res1: Char = z

Note that a Char in Scala (and Java) is Unicode UTF-16 which means that it is 2 bytes. You might lose information!
