Reviving an older thread - still a problem.
What is the current, proper means of inputing an unbreakable white space?
1. in math mode;
2. in text mode.
(I suggest that the same symbol should work in both cases).
Use of unicode nbsp can be problematic (and sometimes unreadable).
Minimal example:
\chapter{X~ray} % OK
\startchapter[title={X~ray}] % no good - shows "~" in the bookmarks!
(of course, the examples above are "silly" as such a short word would
not get broken, unless the width was *really* small...)

Is there any difference between "THIN SPACE" and "NARROW NO-BREAK SPACE" in ConTeXt? Should there be a difference (perhaps "THIN SPACE" breakable)?

no surprise, as math has its own spacing model so it all depends on the

I do not have any strong feelings about this, but do believe that "~"
has always provided an unbreakable white space in TeX, both in text
and math mode. I also feel that "~" is more readable than "\,".
The activeness of ~ isn't that important, but there really should be
a non-breakable space in math mode, and an active ~ is the most logical
choice because of 20 years of TeX input. You can pick something else,
but it is definately needed, and it should be shorter than
"\penalty1 \ "
hm, currently ~ is
\penalty \plustenthousand\space
which gives no space in math as spaces are ignored
i have this definition probably for a reason so i tend to be careful
with a change in text mode

I do not have any strong feelings about this, but do believe that "~" has
always provided an unbreakable white space in TeX, both in text and math mode.
I also feel that "~" is more readable than "\,".
