python-3.x - PDFPlumber 返回符号和不准确的文本

Question

我正在尝试使用 PDFplumber 从 pdf 文件中提取文本

import pdfplumber
pdf = pdfplumber.open(r"https://www.lupin.com/pdf/financials/subsidiaries/multicare-pharmaceuticals-philippines-inc-philippines-2018.pdf")
for ps in pdf.pages:        
print(ps.extract_text(y_tolerance=20))

但是，我得到的输出如下。它没有拾取确切的文本并返回符号-

由于y_tolerance. 提取文本时，pdfplumber添加换行符，其中doctop一个字符与下一个字符之间的差异doctop大于y_tolerance。要解决此问题，您可以删除参数，如

for ps in pdf.pages:        
    print(ps.extract_text())

由于右下角的条形码和 PDF 中的项目符号，出现了奇怪的符号。如果您尝试复制任何页面上的条形码，您会得到奇怪的 emoji unicode 字符。如果你不想要它们，你可以简单地替换它们。
