Can't view the corresponding text from font file

[CodePythonFollow]

I extracted the fonts using the method below

fonts = page.get_fonts(full=True)

for font in fonts:
    res = file.extract_font(font[0])

I use the following method to obtain text information

blocks = page.get_text("dict", flags=11)["blocks"]
for b in blocks:  # iterate through the text blocks
    for l in b["lines"]:  # iterate through the text lines
        for s in l["spans"]:  # iterate through the text spans
            print("")
            font_properties = "Font: '%s' (%s), size %g, color #%06x" % (
                s["font"],  # font name
                flags_decomposer(s["flags"]),  # readable font flags
                s["size"],  # font size
                s["color"],  # font color
            )
            print("Text: '%s'" %  s["text"])  # simple print of text
            print(f"box: {s['bbox']}")  # simple print of text
            print(font_properties)

out:

I can't see the corresponding text in the extracted font. font type: cid

The text "重要提示" not in font file.

I wonder if something went wrong with me？
