Hello Germán May I ask you to give some indication where Unicode is used in WebClient. I'd like to have a look at it and focus on that for the Unicoed porting layer.

Hi Hannes:
I was just responding the other mail where you mentioned me. Some methods where WebClient call UTF8TextConverter or squeakToUtf8 are: WebRequest >>send200Response: WebRequest >>send400Response WebRequest >>send404Response: WebRequest >>send500Response: WebSocket00>>send:type: WebSocket07>>firstFragment: Websocket07>>lastFragment: Websocket07>>nextFragment: WebSocket07>>send: WebClientServerTests>>testStrings Cheers.

Thank you for the list. This makes things easier. So easy things first:
In send400Response "Send a 400 bad request response" | message | message := '<html><head><title>400 Bad Request</title></head><body>', '<h1>Bad Request</h1> <p>The server encountered a request it did not understand. </body></html>'. self sendResponseCode: 400 content: message squeakToUtf8 type: 'text/plain; charset=utf-8' close: true message squeakToUtf8 can safely be replaced with message No call to #squeakToUtf8. The message is an ASCII only string and ASCII is compatible with UTF8. I.e. every ASCII file (lower ASCII, up to code 127) is automatically a UFT8 file. --Hannes On 2/5/13, Germán Arduino <[hidden email]> wrote: > Hi Hannes: > > I was just responding the other mail where you mentioned me. > > Some methods where WebClient call UTF8TextConverter or squeakToUtf8 are: > > WebRequest >>send200Response: > WebRequest >>send400Response > WebRequest >>send404Response: > WebRequest >>send500Response: > WebSocket00>>send:type: > WebSocket07>>firstFragment: > Websocket07>>lastFragment: > Websocket07>>nextFragment: > WebSocket07>>send: > WebClientServerTests>>testStrings > > Cheers. > Germán. > > 2013/2/5 H.

Further analysis shows that all the eight cases can be reduced to one
of the two calls aString squeakToUtf8 aString convertToWithConverter: UTF8TextConverter new So the next step is to check how this is implemented in Squeak. --HJH On 2/5/13, H.

For the method
squeakToUtf8 "Convert the given string (self) to UTF-8 from Squeak's internal representation." ^UTF8TextConverter encodeByteString: self We have a direct Cuis replacement #iso8859s15ToUtf8 I wonder if this is a relict of an earlier version of Squeak for which WebClient was written for. The Squeak class comment for Character says "I represent a character by storing its associated Unicode. The first 256 characters are created uniquely, so that all instances of latin1 characters ($R, for example) are identical. The code point is based on Unicode. " --HJH On 2/5/13, H.
