Carbon Emacs: strange unicode abbreviations

[Makarius]

Carbon Emacs 22.2.1, working with "Unicode Tokens"; typing something like print_theory produces prℤ_theory

It seems that the unicode abbreviation code does not take the surrounding syntactical context into account.

In some situations abbreviations seem to work -- I have no idea yet how to reproduce either behaviour reliably.

[David Aspinall]

I don't think the input method is context sensitive, it is simply based on characters that you type rather than buffer replacements.

We should probably get rid of these word abbreviations. They are supposed to be triggered only by a preceding backslash (TeX-style).

[Makarius]

It works if the backslash is properly escaped -- elisp strings are expected here.
