Activate Unicode collations in Windows version.

What we need to be able to set in myisamchk is
actually a collation, not a character set. This
fix just changes to display the proper error message. 

independently from the expression it is initialized from.
In other words, this change treats a user variable like
a table with one column and one record. Discussed with 
PeterG, Serg and Lars. This change also simplifies replication
allowing not to replicate variables' coercibility.

  Treat unknown characters straight in a query as syntax error, rather skipping it as a space character.

  optimize test_if_minus() when not UCS2 support is compiled.

  Fix compiler complaint.

  Bugs: #8385: utf8_general_ci treats cyrillic letters I and SHORT I as the same

  bug#7571:
  Server & Client characterset are shown under different decriptions
  Switch them into the correct order.
