[Groff] arrowup

[Ted Harding]

Greetings folks,
This one is puzzling me (and it may be that I have missed an
upgrade/bugfix).

I wanted to plant an upward-pointing arrow with the single-line
shaft. In .../font/devps/S (and SS) this is listed as "\[ua]",
PostScript name "arrowup", with octal code 0255 (173 decimal).

However, when I enetered it as "\fS\[ua]\fP" I got the upward-pointing
arrow with the double-line shaft, which is what "\[uA]" should
give (and indeed does, on my system). This has code 0335 octal,
and PostScript name "arrowdblup".

But then, when I changed "\[ua]" to "\N'173'", the decimal code
for arrowup, I got what I wanted.

So either something has changed the numerical encoding of \[ua]
in groff (but despite searching I have found no clue), or possibly
the input characters "\[ua]" were mis-interpreted as "\[uA]".
Could this have something to do with locale?

GNU troff (groff) version 1.18.1
System: Debian Etch Linux, regularly updated.
Locale: LANG=en_GB.UTF-8

Any hints welcome!
Ted.
