$ ../run/john -pot=/Users/magnum/john/rockyou.dupes.utf8.pot --make-charset=../run/all.chr

What's with the 340 dropped? I did not use any filter and only null is excluded from the charset. So what does it drop? It does not seem to be lines longer than PLAINTEXT_BUFFER_SIZE or similar.
In the Rockyou case, simply filtering lines longer than 24 is probably Good Enough[tm] to drop most garbage. OTOH that should probably not happen in charset.c because it would be bad for shorter lengths and other uses than "rockyou.pot".
We also might want to filter out some rockyou-based strings to reduce rockyou-specific bias but that's another issue.
