没有设置字体；

注意，如果是商业使用，注意在pdf中使用可以商用免费的并且可以嵌入pdf的字体；

以思源字体为例；

pdf.add_font('siyuan','',r"C:\\Users\\usr\\AppData\\Local\\Microsoft\\Windows\\Fonts\\SourceHanSansSC-VF.ttf",True)
pdf.set_font('siyuan', '', 100)

from fpdf import FPDF

class PDF(FPDF):
    def header(self):
        # Logo
        #self.image('logo_pb.png', 10, 8, 33)
        # Arial bold 15
        self.set_font('Arial', 'B', 15)
        # Move to the right
        self.cell(80)
        # Title
        self.cell(30, 10, '测试', 1, 0, 'C')
        # Line break
        self.ln(20)

    # Page footer
    def footer(self):
        # Position at 1.5 cm from bottom
        self.set_y(-15)
        # Arial italic 8
        self.set_font('Arial', 'I', 8)
        # Page number
        self.cell(0, 10, 'Page ' + str(self.page_no()) + '/{nb}', 0, 0, 'C')

# Instantiation of inherited class
pdf = PDF()
pdf.alias_nb_pages()
pdf.add_page()
#pdf.set_font('Arial', '', 12)
for i in range(1, 41):
    pdf.cell(0, 10, 'Printing line number ' + str(i), 0, 1)
pdf.output('tuto2.pdf', 'F')

#解决

设置字体，能够匹配汉子的字体库

pdf.set_font('Arial', '', 12)

from fpdf import FPDF

class PDF(FPDF):
    def header(self):
        # Logo
        #self.image('logo_pb.png', 10, 8, 33)
        # Arial bold 15
        self.set_font('Arial', 'B', 15)
        # Move to the right
        self.cell(80)
        # Title
        self.cell(30, 10, '测试', 1, 0, 'C')
        # Line break
        self.ln(20)

    # Page footer
    def footer(self):
        # Position at 1.5 cm from bottom
        self.set_y(-15)
        # Arial italic 8
        self.set_font('Arial', 'I', 8)
        # Page number
        self.cell(0, 10, 'Page ' + str(self.page_no()) + '/{nb}', 0, 0, 'C')

# Instantiation of inherited class
pdf = PDF()
pdf.alias_nb_pages()
pdf.add_page()
pdf.set_font('Arial', '', 12)
for i in range(1, 41):
    pdf.cell(0, 10, 'Printing line number ' + str(i), 0, 1)
pdf.output('tuto2.pdf', 'F')
