1. Anything that requires {heavy wizardry} or {black art} to {parse}:
core dumps, JCL commands, APL, or code in a language you haven't a
clue how to read. Not quite as bad as {line noise}, but close.
Compare {casting the runes}, {Great Runes}.
2. Special display characters (for example, the high-half graphics on
an IBM PC).
3. [borderline techspeak] 16-bit characters from the Unicode
multilingual character set.
