[Seaside-dev] Encoding issues? Entering 'euro sign' into a text input breaks render

[John Thornborrow]

The /seaside/tests/alltests for encoding doesn't pass - it fails with:

"Internal Error

MessageNotUnderstood: UndefinedObject>>asCharacter

RWBinaryOrTextStream>>nextPut:
WAHtmlEncoder(WAEncoder)>>nextPutAll:
ByteString(String)>>encodeOn:
WAHtmlStreamDocument>>print:
WARenderCanvas(WAHtmlCanvas)>>text:
ByteString(String)>>renderOn:
[] in WAGenericTag(WATagBrush)>>with: {[self before. anObject renderOn:
canvas. self after]}

etc.."

I've got the lastest KomHttpServer from squeaksource.com and I'm not
sure what version WAKom* is - I thought this was part of the seaside
package?

I've made a work around, and that is to include:

aCharacter = (Character value: 1069555884) ifTrue: [^ aStream
nextPutAll: '€' ] .

to the list of characters in WAHtmlEncoder class>>encode:on: but given
the ourcome of the last time I made changes to this method, it is not
the preferred/accepted solution.

John
