uft-8 MAFileModelHandler

In Pier on Seaside 3, if I use a utf-8 encoded Comanche Adapter, I receive a walkback "MNU: ByteArray>>isByteString" The error is generated from: GRPharoUtf8CodecStream>>nextPutAll nextPutAll: aString binary ifTrue: [ stream nextPutAll: aString asString ] ifFalse: [ aString isByteString ifTrue: [ self encodeFast: aString ] ifFalse: [ self encodeDefault: aString ] ] while trying to serve "style.css" which originates from: PRStructure>>defaultEnvironment ^ (PRPage named: 'environment') addChild: ((PRFile named: 'style.css') filename: 'style.css'; mimetype: 'text/css'; contents: '/* blueprint patches */........ To reproduce: 1 Download the one-click 3.0a5 release from seaside.st 2 Select utf-8 encoding on the WAComancheAdapter (right click within Seaside Control Panel -> Encoding...) 3 Browse to localhost:8080/pier There seem to be a number of places where a fix could be made, but I'm not sure which (if any) would be the most appropriate: * MAFileModelHandler>>handleFiltered - the GRPharoUtf8CodecStream response stream is created, without utf-8 encoding, a GRNullCodecStream is created instead. * PRFile>>contents: perhaps PRFile shouldn't always convert the contents to a ByteArray * Perhaps ByteArray should implement isByteString. Any thoughts? Nick
