R help - Dec 2007 - non-ascii characters in TclTk

Greetings, R-Helpers:

A year ago or so I was able to use the non-ascii character ? in my TclTk.
(You can type it on Windows as <alt>0226)  I can use something like
expression(hat(a)) elsewhere in R, but I seem to be doing something wrong
when I try that syntax in TclTk.  The widget will run but it displays
something frightening like R-call_lang 019C8480 019A7724 where I expected to
see ?.

Can anyone suggest how to use the a with caret in a TclTk widget?

Thanks.

Nothing frightening or unexpectable about that.... If you pass an 
expression, Tcl will think it is a callback. You shouldn't expect 
plotmath features to work outside of plots.

Can't you just type it in inside a string? Otherwise, Unicode escapes 
like "\u00e2" should do it.
