I also have a similar problem.
MyFlext Client-side and InDesign Server( http://localhost:18555/service?wsdl ) to pass parameters, there will be produced garbled.( Chinese UTF-8 )Some people can solve it?
I have successfully circumvented the problem by encodeing the parameter stings with base64 before sending (in c#) by using:
string parameter = System.Convert.ToBase64String(System.Text.ASCIIEncoding.ASCII.GetBytes(toEncode));
, and then decode in the ID script before using them.
But this is just a hack.
UTF-8 should work.
Is the script you are sending saved as UTF-8 or platform encoding? (needs to be UTF-8)
Is this on Windows or Mac? Which version of the OS? If Windows, is your console's code page set to UTF-8 (chcp 65001)? If code page is 65001, is the font in the console a non-raster font?
Does the same script work correctly when sent to IDS via 'sampleclient'?
Can you provide a sample script that fails?
