[LON-CAPA-users] Could not process request

Thu, 14 Jul 2005 16:19:04 -0400

Hi All,

Further analysis: the offending character was produced by this entity:

&#956;

- that was meant to produce a "micro", but somehow was interpreted as  
unicode (probably after being expanded into binary by the parser),  
and then subsequently choked upon because of course it is not valid  
unicode. I replaced it by "micro" as in

<resource src="/res/sc/gblanpied/courses/usclib/hrw/chapter26/ 
hrwc26p63.problem" id="18" title="You have several 2.0 microF  
capacitors">

- did the trick.

- Gerd.
