[2005] multi language web service problem

Hello all,
i am building a web service which is supposed to return a description string based on an ID parameter. the problem is data can be stored in several languages in SQL SErver database. inside the database itself, the field is defined as ntext so Language marks are not lost inside the database.

language special marks like german and russian characters are lost while returning them from the webservice.

the webservice has a method that should return a string value retrieved from the database. it works very fine with english language but when it retrieves german or russian or arabic language it replaces severa, characters with ????

i am sure the data is stored right in the database as i already retrieved them using a windows application.

anyone knows how can i make the web service supports several languages output ???

thank you all in advance
