If you have ANSI encoded documents, there are no information about code page and ANSI can contains one encoding only.
Unicode encoding allows you to store multiple encoded text in one document, so you can have part of text in chinese, part in russian, part in your language. If want to open e.g. russian encoded document, the easiest way is allow Autodetect CP in the Encoding menu. As alternative after you open document and see that it displays wrong chars, you can change code page in the encoding manually and reload document (Ctrl+R). For russian, choose ANSI Cyrilic (1251), for Chinese you can use ANSI Simplified chinese (936) or ANSI Traditional Chinese (950) (Cantonese or Mandarin). You have to know what to use. If Chinese isn't included in the Encoding menu, click on the bottom to Modify and check checkboxes before languages you want to use and as oposite you can uncheck ones you don't want to see in menu Encoding. -- <https://forum.pspad.com/read.php?2,77845,77853> PSPad freeware editor https://www.pspad.com
