Error on Chinese Characters text fetching!!! any idea to resolve it?

[marcusau]

Hi , I am using the module to fetch texts (combination of both English and Chinese) from the pdf files, with the following error:

from pyxpdf import Document, Page, Config
from pyxpdf.xpdf import TextOutput, TextControl, page_iterator
with open(pdf_file, 'rb') as fp:
    doc = Document(fp)
for page in doc:
    res_box =page.find_text('Cornerstone', search_box=[0, 0, 400, 400], case_sensitive=True)
    if res_box:
        print(page.label,res_box)

results:
