About changing LCD localization, garbled?

[hyi1233]

According to god's instructions, after the LCD display is modified to Chinese, garbled characters appear in the interface menu. What else should I do?

#define LCD_LANGUAGE zh_CN

There are no Chinese chars available in the integrated font and current version of Profesional firmware.
For Chinese support you should use the DWIN_LCD_PROUI version from official Marlin repository.
