Hi Sony,
does the issue depend on the user or the client machine?
i.e.: if you log in on the same machine (and, if using Citrix or something similar with the same citrix account) as your colleagues, whi can see the texts, then it's definitely a codepage issue on your PC, which needs to be solved by PC support.
In that case: do also check printers. You might be able to see it printed or your colleagues might the ####, when they print, even though it's ok in the screen.
