Hi @fangjiyuan - can you perhaps show what should be extracted exactly?

I see one long number in the text:

>>> [ word for word in words if '193' in word['text'] ]
[{'text': '19306498777',
  'x0': 339.75,
  'x1': 389.25,
  'top': 143.61997000000008,
  'doctop': 143.61997000000008,
  'bottom': 152.61997000000008,
  'upright': True,
  'direction': 1}]

But I don't understand the language to know if that is the phone number or not.

I can get this text too. But the page 2 of pdf contains phone number can't be find in the red outlined area .

[cmdlineluser]

Ah okay. So the problem is on page 2 of the updated PDF.

Yes, I get the same behaviour.

It appears none of the numbers inside the [] are detected.

>>> page2 = pdf.pages[1]
>>> print(page.extract_text())

FWIW, it seems that the same text is not copy/paste-able from a standard PDF viewer into a plain text editor. I haven't examined the potential cause closely, but this suggests the issue might not be solvable via pdfplumber.

It's possible (but just a guess) that this might be caused by glyph remappings, c.f., #851 (comment)
