This excerpt is part of the text file of ‘The Inauguratory Classic of Acupuncture and Moxibustion’《针灸甲乙经》, which I have and to know if you happen to decode the text correctly, I believe ƒÍ∑›£∫π´‘™256ƒÍ should be 年份：公元256年 or something along the lines of that

As part of this task, I have a few files that I would like to be restored to the Chinese character version
