Python fpdf 没有给出正确的输出

使用 fpdf 模块时，问题在于使用特殊字符，例如“ć，č，š，đ，ž...

我尝试了这样的简单代码：

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.set_font("Arial", size=15)
f = open("data.txt", "r")
for x in f:
    pdf.cell(200, 10, txt=x, ln=1, align='C')

pdf.output("mytestdata.pdf")

引发的错误是：UnicodeEncodeError：'latin-1'编解码器可以' t 对位置 77 处的字符 '\u2021' 进行编码：序数不在范围(256)

当我使用 with open 读取文本文件并使用 decode 对其进行解码时latin-1，输出错误。

with open("data.txt", 'rb') as fh:
    txt = fh.read().decode('latin-1')

字母与特殊符号混合在一起。但这是不引发 UnicodeEncodeError 的唯一方法。

data.txt 的内容：

test1: Čč
test2: Ćć
test3: Žž
test4: Đđ
test5: Šš

When using fpdf module, problem is with usage of special characters like 'ć,č,š,đ,ž...

I tried simple code like this:

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.set_font("Arial", size=15)
f = open("data.txt", "r")
for x in f:
    pdf.cell(200, 10, txt=x, ln=1, align='C')

pdf.output("mytestdata.pdf")

Error raised was: UnicodeEncodeError: 'latin-1' codec can't encode character '\u2021' in position 77: ordinal not in range(256)

When im using with open to read text file and decode it with latin-1, output is wrong.

with open("data.txt", 'rb') as fh:
    txt = fh.read().decode('latin-1')

Letters are mixed with special simbols. But it is the only way where UnicodeEncodeError is not raised.

Content of data.txt :

test1: Čč
test2: Ćć
test3: Žž
test4: Đđ
test5: Šš

添加对 Unicode 字体的支持，并确保以保存的编码读取文件。还要从从文件读取的行中删除尾随换行符，因为它也会出错。

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.add_font('Arial', '', 'c:/windows/fonts/arial.ttf', uni=True)  # added line
pdf.set_font('Arial', size=15)
with open("data.txt", encoding='utf8') as f:
    for x in f:
        pdf.cell(200, 10, txt=x.strip(), ln=1, align='C')

pdf.output("mytestdata.pdf")

结果：

PDF 结果

Add support for a Unicode font and make sure to read the file in the encoding it was saved in. Also strip the trailing newlines from the lines read from the file as it made errors as well.

from fpdf import FPDF

pdf = FPDF()
pdf.add_page()
pdf.add_font('Arial', '', 'c:/windows/fonts/arial.ttf', uni=True)  # added line
pdf.set_font('Arial', size=15)
with open("data.txt", encoding='utf8') as f:
    for x in f:
        pdf.cell(200, 10, txt=x.strip(), ln=1, align='C')

pdf.output("mytestdata.pdf")

Result:
