Got Issue with Font Khmer Unicode.

[kuth-chi]

I have add_font with the code below:
` def chapter_body(self, name):
with open(name, 'rb') as fh:
txt = fh.read().decode('utf-8')
# set font
self.add_font('KhmerOS_content', fname='font/KhmerOS_content.ttf')
# self.add_font('content', 'B', fname='font/static/NotoSansKhmer/NotoSansKhmer-Bold.ttf')
self.set_font('KhmerOS_content','', size=12)

    self.multi_cell(0, 10, txt)
    self.ln()
    # end each chapter
    # self.add_font(fname='font/Norasi-Italic.ttf')
    self.set_font('helvetica', 'I', size=14)
    self.cell(0, 5, 'End of Chapter')`

But it is working not properly (Not support Khmer characters)
You can find result with attachment for detail.

Hi @ezzhop

Note that PyFPDF is not maintained anymore.
fpdf2 is its successor: https://pypi.org/project/fpdf2/
We have work ongoing to support more font types, and supporting ligatures:

Hi @Lucas-C
Thank you the information.
I have installed FPDF2 to my project.
But still problem with Khmer OS font is an Unicode UTF-8
def chapter_body(self, name): # Reading text file: with open(name, "rb") as fh: txt = fh.read().decode("utf-8") # Setting font: Times 12 self.add_font('KhmerOS Moul', fname='font/KhmerOSMuol.ttf') self.set_font("KhmerOS Moul", size=12) # Printing text in a 6cm width column: self.multi_cell(60, 5, txt) self.ln() # Final mention in italics: self.set_font(style="") self.cell(0, 5, "(end of excerpt)") # Start back at first column: self.set_col(0)

and also got an error message.
UserWarning: Core font or font already added 'khmeros moul': doing nothing warnings.warn(f"Core font or font already added '{fontkey}': doing nothing")

I hope got a solution about this, Thank in advance.

Hi @ezzhop! 😊

If you have an issue with fpdf2, please report it by opening a dedicated issue on the fpdf2 project GitHub page: https://github.com/PyFPDF/fpdf2/issues

Please take care to provide a minimal reproducing example, including mention of where to find the TTF font files used: https://stackoverflow.com/help/minimal-reproducible-example
Something along the lines of this snippet:

from fpdf import FPDF

pdf = FPDF()
txt = """..."""
self.add_font(fname='font/KhmerOSMuol.ttf')
self.set_font("KhmerOSMuol", size=12)
self.multi_cell(60, 5, txt)
pdf.output("khmer-rendering-issue.pdf")

Also, please understand that neither me nor other fpdf2 contributors know khmer language.
Hence, could you try to be very specific on the issue you are facing please?
I understand that some characters are not rendered correctly, but could you please answer those questions:

• are the characters simply missing in the rendered PDF document, or do they get replaced by something else visually?
• does it always happen for the same characters? Which ones?
• are there ligatures in khmer language?
• have you checked the existing fpdf2 issues regarding fonts, unicode & ligatures? https://github.com/PyFPDF/fpdf2/issues?q=is%3Aissue+is%3Aopen+label%3Afont+sort%3Aupdated-desc And is your problem linked to some existing issue?
