About web script decryption

A netizen gave me an encrypted webpage named "Taiyi Qianyi", with the script being added using Microsoft tools. encode], said that the decryption software can not be decrypted, I found that the page code is UTF-8, changed to ANSI, the use of scrdec smooth decryption, it seems that the encoding problem sometimes full of useful, if the decryption fails, you can try to check the encoding format, because the current decoding tool seems to be for ANSI encoding!
