The '09 mail is the one I remembered. I thought Unicode supported obsoleted this, but apparently not.

So, back in 2009, Andreas proposed:
What I would propose to do here is to define that "leadingChar = 0" which currently means "Latin1 encoding, language neutral" is being redefined to "Unicode encoding, language neutral". What this does is that "Character value: 353" and "Unicode value: 353" become the same, if the environment is considered language neutral which by default it would be.
In 2010, he pushed this into Squeak Trunk.
Then, in 2011, there was a conversation where Andreas stated:
On 1/8/2011 2:16 AM, Sean P. DeNigris wrote: #leadingChar "In Squeak Character encoding, bits above 16r3FFFFF don't encode the character, but hold information about the language environment and the encoding which should be used to interpret the charCode. The background of which is Han unification (http://en.wikipedia.org/wiki/Han_unification)."
How's that as a method comment? Is it really "In Squeak... encoding..." or does this apply to unicode in general?
It is Squeak specific. Unicode does not have a leading char.
Cheers,
- Andreas
Maybe this later email was the one that you were interested in?
I can't find any mention in the commit list or other discussions where the leadingChar was dropped, but I'm not an expert in this space (just interested).
Thanks, cbc

But what if I just upload packages that (1) add copies of these methods with the name spelled correctly to String and ByteString, (2) change the senders in MOFile and (old) XMLParser to use the new correctly spelled messages, (3) change the incorrectly spelled (old) XMLParser extension methods to just send the new, correctly spelled messages?

Removed sends of the old XMLParser's applyLanguageInfomation: (sic) from MOFile that I don't believe is still needed (it's leadingChar-based)
Did we replace the leadingChar mechanism with something else?
not that I know. Monty?
