dashboard mishandles utf-8 in description

[rsc]

the dashboard is showing right now a CL titled

A+C: Jose Luis V?zquez Gonz?lez (individual CLA)

the ? are supposed to be á characters.  
the problem is that the dashboard runs hg to 
get the CL description without setting HGENCODING=utf-8 
in the environment, so hg limits its output to ascii
(surprise!).

the fix is to set HGENCODING in the execution environment
(and to convert all the builders to use the go program).

Comment 2:

I doubt very much that that would fix it.
The fix is to set HGENCODING=utf-8 in the
environment when invoking hg from the
builder program.
