All characters of the c# application shown as square character in only one computer

I have a .net 3.5 application written in c# and 开发者_JAVA技巧it works fine except in one windows 2003 server. In that server all characters of the application shown as square characters. i have another windows 2003 server with exactly the same regional settings but application works fine in that server. Also when i copied the square characters to an another application characters shown as normal. What can be the reason of this problem?

Sounds like you're missing a font, or a regional setting on that machine. Find out what fonts are you using in your app, and/or compare the fonts directories between the machines.
