Encoding error in QT Creator when including glm header files - c++

Question

I'm including GLM header files in a QT project in QTCreator, but I keep getting encoding errors. All files seem to be set to UTF-8 and they are displayed normally on screen. I get several messages as the following:
C:\Users\Luís Longo\OneDrive\Dyno3D\linking\glm\detail\type_mat2x3.inl:-1: In member function 'glm::mat<2, 3, T, Q>::col_type& glm::mat<2, 3, T, Q>::operator[](glm::mat<2, 3, T, Q>::length_type)':
C:\Users\Luís Longo\OneDrive\Dyno3D\linking\glm\detail\type_mat2x3.inl:222: error: converting to execution character set: Illegal byte sequence
assert(i < this->length());

Answer 1

It seems the problem was due to the filepath, which has a "í" character. Changing the project folder has solved the problem.
