Spaces+in+labels+of+ARFF+files

= Spaces in labels of ARFF files = A common problem people have with ARFF files is that labels can only have spaces if they are enclosed in single quotes, i.e., a label such as: code format="text" some value code should be written either code format="text" 'some value' code or code format="text" some_value code in the file.

See single quotes in labels of ARFF files for an example using the Weka API for automatically quoting such strings.
