I just got a new system, Windows 7 Home Premium, installed Notepad++ and used it for a few days. I wrote some html/php files in Chinese, saved as UTF-8 without BOM. Uploaded to server and tested, all is well, until now.
Somehow, Notepad++ would not display the chinese characters in the editor anymore and all it shows are squares. Playing with the encoding conversions etc. doesn't help. So far, it felt like a Notepad++ bug.
Then I downloaded and installed Komodo edit. Same thing happened. Copying and paste chinese text from a chinese website like sohu.com into the editor will show squares as well.
Then I try notepad.exe, same issue. But it works in Microsoft Word and Wordpad.
The only big thing I did before this issue crops up is installing SQL Management Studio 2008 x86. Would this have any effect on the system? Maybe it changed the database locale and everything else?
Anyone have any idea how to fix this? I remember in older versions of Windows, there is an option in Regional Language settings to "extend language settings to other programs" something like that. But I cannot find it anymore in Windows 7.
EDIT: I found http://www.sevenforums.com/general-discussion/186507-chinese-characters-display-squares-text-editors.html which says to create a new profile. I haven't try. But to go that way is ridiculous....
