Download the paper template from the Internet, found that directly double-click Open. tex file (the default association with Winedit Open) will appear reading error, and then see no text (online someone to discuss open is garbled problem, but my is completely not see anything), my system Win7, It seems to be related to the Utf-8 code, because utf-8 files are not open, such as I use JABRAF generated by the Chinese bib file (utf-8 code) also can not open.
Workaround:
1. If it is a UTF-8 encoded document, first open WinEdt, then click on the File menu-open, and then find your document folder, the lower right corner of the button above the default to open the black triangle, select the appropriate encoding, estimated that your document is Utf-8, And then open it again.
2. Under Windows, open with other Tex tools, such as MiKTeX's own texworks
3. Under Windows, open with the Text tool, copy the contents, create a new Tex document with Ctex (WinEdt), and then copy the contents.
