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，我得到的输出如下所示。它不会提取确切的文本并返回符号-

因为y_tolerance的值太高，所以没有提供确切的文本。提取文本时，如果一个字符的doctop与下一个字符的doctop之间的差异大于y_tolerance，则pdfplumber会添加换行符。要解决此问题，可以删除参数，如下所示

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

奇怪的符号出现了，因为右下角的条形码和PDF中的项目符号。如果你试图复制任何页面上的条形码，你会得到奇怪的表情符号unicode字符。如果您不需要它们，您可以简单地替换它们。
