Summary: Error break with rtestezunits.mac

Initial Comment:
Maxima version: 5.20post
Maxima build date: 21:53 4/2/2010
Host type: i686-pc-linux-gnu
Lisp implementation type: SBCL
Lisp implementation version: 1.0.29.11.debian


I get an error break when I execute the share_testsuite:

   Running tests in rtestezunits: 
   Caused an error break: rtestezunits

It seems to be an old and perhaps known problem, but I have never reported it.

The last correct example is problem 55:

********************** Problem 55 ***************
Input:
[declare_constvalue(%C2, 14390.0), declare_constvalue(%C1, 3.742e+8)]


Result:
[14390.0, 3.742e+8]

... Which was correct.
Maxima encountered a Lisp error:

 decoding error on stream
 #<SB-SYS:FD-STREAM for "file /home/dieter/workspace/mymaxima/temp/rtestezunits.mac" {C28DA41}>
 (:EXTERNAL-FORMAT :UTF-8):
   the octet sequence (181) cannot be decoded.

This is the example 56 which causes the error break of the share_testsuite:

declare ("�", alphabetic);
done;

I get no error when I execute the above example from a command line. The example 56 and the following examples seems to work:

(%i3) declare ("�", alphabetic);
(%o3) done

(%i4) (C1: %C1`W*�m^4/m^2, C2: %C2`�m*K, l: %l`�m, T: %T`K, 0);
(%o4) 0

(%i5) expr: C1/(l^5*(exp(C2/(l*T)) - 1)), infeval=true;
(%o5) %C1/(%l^5*(%e^(%C2/(%l*%T))-1)) ` W/(m^2*�m)

Message:
The non-ascii character which appears in rtestezunits.mac is supposed to be
a small greek mu, but it does not decode to any valid UTF-8 character
(that's what SBCL complained about). I have replaced the offending
character with an equivalent name using only ascii characters (namely
"micron"). Fixed by r1.19 rtestezunits.mac. Closing this report as fixed.
