Is this called texture atlas? Or is that something different? I am not a CL expert :)
The other thing we need to worry about is the matching length. Let's say we start matching parallelly from the first 128 starting offsets, but the matching length is not known at compile time. It can be 100 bytes, 1000 bytes, anything. Are you able to do that without uploading the whole input, which is the worst case? E.g: /\p{Any}*/ matches the whole input.
