This is Step One of several in a series of posts. It’s simple, really.
Every mail package can sense what character set that’s being used by an email message’s sender. As an example, the language you’re reading is a “Latin language derivative”. Cyrillic, as an example, is meaningless to me. I have respect that it’s understood by millions of people. Not me. Therefore, let me opt out of getting any messages that contain Cyrillic characters/fonts. The same goes for Chinese, Japanese, Korean, Thai, Urdu, Hebrew, and Arabic. Instant trash can.
The Internet, whether we like it or not, was initially formed with 7-bit ASCII character sets. It’s not terribly tough to allow users to simply vaporize character sets that they can’t read/don’t use. It’s that simple. No one’s thought of it, which makes me crazy. Step Two comes tomorrow.
