VTFF

VTFF is an esoteric programming language created by User:Programmer5000. It uses only 2 characters,  and , which are Vertical Tab, and Form Feed respectively.

Pre-intepreting
First, all non VT or FF characters are removed from the code.

Then the code is separated into chunks of VTs (eg, the code is split on FFs).

For example, if the code is  (replacing V with a vertical tab and F with a form feed), than it would be converted into ,   and.

Char converting
Next each chunk of VTs is converted into the UTF-8 codepoint of its length plus 31.

For example, for the chunk is, than it is converted to the UTF-8 character at 2 + 31, which is.

The result is a list of UTF-8 characters, in this case,  , and.

Evaling
Lastly, the code is joined to form a string ( in this case) and  uated as Javascript. In this case, it is a syntax error.
