Re: st: reading HTML source in Chinese but get a messy code |

Tony, after visiting the link I see in lines 2-9 characters in Chinese. Stata will not show you these characters because Stata does not work with unicode. To see the file through Stata's eyes, go to the link you posted in FireFox, then go to the menu View-->Character Encoding-->More Encodings-->West European-->Western(Windows-1252). This is what you can import into Stata and, yes, it does look messy. This is the best you can get with it. The good thing is that if you process your data in Stata and then output the same messy text you will end up with a very readable text, but readable elsewhere (e.g. in notepad or a browser). To cut it short, if your analysis requires e.g. search of a substring in a text - you might do it by searching for byte sequences, and those sequences would not look intuitive at all. But if it is something more involved then you might want to rethink the choice of a package to do it. Perhaps if you describe the broad goal of what you are doing it would be easier to advise.
