Great ! Thx a lot - works fine now:

# Add local copy of BuildFormatString
cp -av share/html/Search/Elements/BuildFormatString \
	local/html/Search/Elements/BuildFormatString

# Add NBSP
local/html/Search/Elements/BuildFormatString:
	     NEWLINE
	+    NBSP
	); # loc_qw


** Advanced (-:
One additional question - could this be done by using a callback ?
I saw a callback directly after the definition of the fields ...
    $m->callback( CallbackOnce => 1, CallbackName => 'SetFieldsOnce', Fields => \@fields );

I tried to create a callback - but it does not work (sorry, I never
used Callbacks). May you can give me a small hint ?

cat /opt/rt3/local/html/Callbacks/MyCallbacks/Prefs/SearchOptions.html/SetFieldsOnce 
<%init>
  push @fields, "NBSP";
  RT::Logger->debug("SetFieldsOnce.1: \n");
</%init>
<%args>
  @fields => undef
</%args>

Kind regards
