The text variable allows a maximum text length of 1024 characters (2K bytes), the actual text display length depends on three conditions: the text length limit (the word length in the property setting), the text terminator 0xFFFF, or the end of the text box, and the display will end when any of these conditions is encountered. Therefore, when setting the word length to be greater than the actual text display length, when writing the text display with the 0x82 command, the text terminator 0xFFFF must be written at the end of the text, otherwise, extra information will be displayed at the end of the text.
