Hi Bob,

First off, has stl_algo.h been modified lately?
Something must have changed.

\240 == 0xa0 displays in both xemacs and emacs as a space.

In emacs with the cursor at the beginning of the file type this:

M-: (search-forward "\xa0")

I.e., ask this lisp interpreter to evaluate (search-forward "\xa0")

(There's probably some way to enter this using M-x, but I couldn't get
the quoting right.  Getting a raw eval prompt worked)

If it finds the character, it will move point there and return the
buffer offset of the character.  C-d will delete the char.

FYI, you can insert a \240 using M-: (insert 160)

----

Or you could try M-x hexlify-buffer.
(I'd probably narrow the buffer to the single line in question before
using hexlify-buffer.)  Use M-x hexl-mode-exit to get back to your
normal mode.
