Re: Unicode allowables in Environment variables

[William DeShazer <earl.deshazer@xxxxxxxxx>]

You mentioned, or the issue that you referenced, mentioned that it was a zle interaction. I think candidates for odd insertions would be insert_unicode_char, insert-composed-char, expand-absolute-path, bracketed-paste-magic, send-invisible. While those look interesting as candidates, the zle is only involved with handling strings if it has been invoked, correct? I’m not sure there is a logic path to trigger these kinds of events. I figured I should mention it, since you have a better knowledge of the code-base than I do.

On a separate but possibly related note, More frequently lately, I have been having a heck of a time with a tty interrupt that happens when I do command-K, and then ls. The l gets gobbled, and then the tab completion on the ’s’ engages the tty interrupt. I have been reticent to explore it, however if the zle is injecting/transforming characters randomly, these issues could be related. I can’t reliably reproduce it and if we solve this issue, maybe the other will mysteriously go away. Wishful thinking.
