Anyone that have a general algoritm to filter out emoji from sender addresses?
It's possible that the problem isn't specific to emojis but to any unicode code point in the supplementary planes (code
point values above U+FFFF). Applications which were written when unicode was 16 bit only may have problems.
So one possible method would be to identify such code points and replace them with something that works in 16-bit
unicode, such as the character code U+FFFD which is normally rendered as �.
Where to apply such a filter would largely depend on your specific mail setup. I can imagine that a small milter might
do the trick.
However, getting the users to update their MUAs to something from the current
millenium might not be a bad idea after all...
Cheers,
