question:

how can I generate pics with chinese characters with local font settings? (ignore environments)

Comienza ejecutando el fragmento de Python proporcionado e inspecciona cómo mplfinance y Matplotlib gestionan la fuente SimHei configurada. Confirma si el título chino se renderiza sin las advertencias indicadas sobre glifos faltantes, tratando la ruta del backend de PyCharm como contexto ambiental que debe ignorarse.
