[Seaside] Re: TableReport slow down

[Bob Arning]

Sounds like an encoding issue. Your code inserted into my app produced a 
euro sign where I had been printing a fancy leftarrow. This is a much 
older seaside and has a GRNullCodec as the codec of the requestContext. 
If you are using a different codec, then it may be thinking your utf8 
euro sign is really 3 oddball characters and rendering them separately. 
Perhaps you can do something with the codec (like use a null?).
