Does your text file open up and look like a bunch of weird characters and gibberish? It's probably using a charset that the app you are trying to open it in can't understand.
The Text Encoding Language Converter can convert the text file back to the language you want!
* Auto-detect the language and encoding that your text file is in
* Supports virtually all charsets through ICU4J, such as GB18030, BIG5, etc
* Open the converted file in the app of your choice
* Converts large files quickly
