> and annoyingly restrictive
How so? In what scenario would you ever need to use a sequence like <tab><space><tab> in indentation in your source code? Let alone using esoteric Unicode whitespace characters for indentation. I think it is perfectly reasonable for the language to make the restriction that indentation must be either all tabs, tabs followed by spaces, or all spaces.

Writing a lisp in an editor that doesn't do boneheaded things with tabs? That's the only one I've personally run into but lack of imagination is hardly a good excuse to implement arbitrary restrictions.

How do you know what's esoteric in other countries? I certainly don't. I'm not an expert in linguistics but I'm sure that people everywhere in the world write computer programs at this point.

Without any concrete justification? Why would entirely artificial restrictions ever be seen as reasonable?
What "boneheaded things with tabs" are you referring to? The picture I'm piecing together from your comments suggests that you may use tab characters in a different way than most people seem to, so I'd quite like a further explanation of how you use tab characters and how you expect an editor to handle them.
> you may use tab characters in a different way than most people seem to
As far as I'm aware there are three primary and entirely independent uses for tabs. Indentation, field separation, and typesetting. When it comes to typesetting and also to display of fields with a narrow maximum width the concept of a tabstop is useful.
Boneheaded things with tabs was in reference to code editors (where tabs are more or less exclusively used for indentation) most often failing to provide the ability to disable tabstop. In practice this generally hasn't been a point of friction because until fairly recently the most popular languages (ie C & co) didn't support constructs that would lead to adding any indentation outside of the prefix of a line.
