[Blackholespam-general] Non ascii character check

[Jag <ja...@uv...>]

Hi,

This check needs to be extended over a patch that originally submitted to include the 
pounds sign (on ascii 163).

I've attached by modified checkascii .c file that I'm running with on prod.

(I've had to allow 0x91, 0x92 and 0x96 through - Some email clients appear to be using 
these for quote and hyphen characters).

Anyway, see the attached .c file.
