Dear Aero, did you test this issual by the following steps?
Step1. Open Inkscape1.3, click the "Create Edit Text Object(T)"
Step2. Draw a sufficiently large rectangular box anywhere in the document. (important step, no this step, no error message)
Step3. Input any text with any text font and any text size, and press 【Enter】 to create a new line. (Make sure create a new line!!!) Step4. Input any text with any text font and any text size. (no metter it is the same as the first line or not) Step5. Save the svg document and close Inkscape software. Step6. Covert svg to pdf with cmd. The error message will show!!!
Open cmd windows, and input the command inkscape --help or input the command inkscape --version, there is no output.
OS Version: Windows10 22H2
inkscape: 1.3
Try
inkscapecom --help
Dear Aero, thank you for your answer, it is resolved. Thank you!!! But an old issual(Invalid glyph found, continuing...) still exists.
No error message when testing issue #8471 in Windows 11.
inkscapecom --export-type=pdf 绘图1.svg
Edit: Sorry, I did not add missing pictures (emojis) to the text. Looks normal in Firefox.
