u3d export latex error

[wim]

Hi,

The u3d export in Meshlab 2025.07 produces a latex file with a superfluous accent in the line "3Dmenu,'".
Compilation ends with an error. An example is shown below.

The issue is located in /main/src/meshlabplugins/io_u3d/io_u3d.cpp on line 305:

latex.write(1,"3Dmenu,'");

This should be

latex.write(1,"3Dmenu,");

Best regards,

Wim
