description: 
when trying to preview a report with a flat file containing unicode surrogate character, all data are not displayed at the preview panel. 
in addition, web viewer has the same problem.

expected: all data are displayed correctly at the preview. 

note: other style documents (ex. word, excel etc.,) displayed data containing unicode surrogate characters correctly.

reproducible: always

steps to reproduce:
1.create a report project. file > new > business inteligence .... > report
project
2. import the attached report design document (surrogatetest_report1.rtpdesign")
4. edit data sources, and added a path to a cvs file contains unicode cjk
surrogate characters.
(test data "surrogate_data.csv" is attached. this file contains u+2000b.
also attached "nosurrogate_data.csv" as the comparative file which does not include surrogate character.)
3. open the surrogatetest_report1.rtpdesign
4. click "preview" tab. all data are not displayed.
