# Case Sensitive Strings

Since this isn't explicitly codified anywhere, and was sparked by discussion surrounding my recent challenge, I figured I'd bring it up here for consensus before modifying the tag.

## The Question

When a challenge asks for a string, what should the default case-sensitivity be?

• This answer hits the nail on the head. If you think about strings as sequence of bytes in a particular encoding, case-insensitivity makes no sense. While whether or not "A" == "a" could be questioned, no reasonable person would think 0x41 == 0x61. – user45941 Jul 2 '16 at 0:01
