while eval, get_defined_chars function can not get any Chinese character data! There is no output.

I gave the font file I downloaded myself, the font is correct and can be installed, but while testing, I found that there is no output pictures, I found that when using “get_defined_chars(fontfile)” function, there are only symbols like “！@#￥%…&×（）” in "chars". So the gen_chars and data_list is empty! I'm so sorry, but why
