Problem exporting japanese characters to a notepad

[enigmat...@gmail.com]

Hi all..

I have been writing a code to provide multiple language support to my
software.
The software has option to take input from text editor.
My problem is that if i input Japanese characters in that text editor
and then export them to a notepad(in CSV format), then the parts of
strings are not displayed properly, tho i have tried BDF Shinonome
Gothic/MS Gothic fonts to dispaly the same.

For example, a line in notepad which should have been displayed as..
104,"メッセージを作成する","hi"

is now shown as
104,"メッセージを作成す."hi"

that is, comma at the end of the string(which is hardcoded while
programming to adhere to the CSV file format) is now displayed as a
dot.

The same problem also appears in VC Compiler, even on a Japanese OS.

What could be the problem??
