Utf-8 doesnt work in IE9 w/o forceJSONP=true

[alim-akbashev]

Messages containing utf-8 (cyrillic for example) cause parse error on client in IE9 (without forcibly enabled jsonp)

I just updated the netty-socketio-demo. You should set utf-8 charset as meta param in your html head section.

didnt help

[mrniko]

do you use 1.3.3 client?

[alim-akbashev]

yep

[mrniko]

(without forcibly enabled jsonp) how did you do that?

(without forcibly enabled jsonp) how did you do that?

i simply did not set forceJSONP: true in io.connect opts in that case socket.io.js uses b64=1 for IE9 (at least IE9, not sure about all other old browsers)

[mrniko]

i have tried both cases: var socket = io.connect('http://localhost:9092', {'forceJSONP': true}); and var socket = io.connect('http://localhost:9092', {'forceJSONP': false}); and didn't encounter any problems with utf-8 encoding.

ok, i'll retry again with latest version from master and will provide test project if issue still exists

i guess no need to publish test project cuz i'm using master branch of backend without any changes + master branch of netty-socketio-demo with only changes - url
