Yes, we'll have a look at it.


> Isabelle/a96bd08258a2 propagates some changes of symbol.scala to its unequal twin in src/Tools/WWW_Find/unicode_symbols.ML, but it could not be tested because the server was producing "500 - Internal Server Error" already before the change. In contrast, in Isabelle2012 the wwwfind tool appears to work.
> Generally, unicode_symbols.ML imposes assumptions on the format of etc/symbols files that were not there before, according to the operational specifcation in symbol.scala.  At some point I also would like to reform this ancient file format, and might end up producing a legacy copy just for WWW_Find.  Management of symbols happens on the Isabelle/Scala side these days.
