- Given: we want to update to 8-bit news.
-
- Also given: quite a few sites will not update, no matter how much we
- scream. How to solve this? Here's a suggestion:
-
- For any news article that has 8-bit characters in it, include a special
- header indicating the fact. This header itself will contain eight-bit
- characters, and will be structured in such a way that it is very likely
- to be trashed by a 7-bit link, but that a recognizable residue will
- come through. Something like:
-
- Character-Set: <stuff with 8-bit characters and a checksum here>
-
- This header can also be used to specify which character set is in use,
- where it matters.
-
- Now there are three cases:
-
- First, the article may go through an 8-bit-clean link. If so, it comes
- out OK.
-
- Second, the article may go through a 7-bit link with intelligent
- system administrators on both ends. The articles are encoded using
- some protocol and decoded on the other end, so that an 8-bit-clean
- link is produced on top of a 7-bit channel.
-
- In either of these cases, the article comes out unscathed. The final case
- is the one everyone is worried about: such articles go through a seven-bit
- link using old software. At the other end, the Character-Set header is
- altered: the leading "Character-Set:" comes through, but what follows will
- not be correct. Sites with up-to-date software know that such articles
- are likely to be corrupt, and simply drop them on the floor.
