The main reason why symbols are misplaced or garbled is that different computers have different font settings.

2, treatment:

(1) Hold down the CTRL key in PPT, and then select the text boxes of input symbols in turn, and set their fonts to the fonts that come with the system, such as Song Ti, and then right-click: Combination-Combination, so that the fonts, sizes and distribution positions of these symbols can be fixed and garbled can be avoided.

(2) If you really need to symbolize the effect of the original font, you can package the PPT into a CD, and check "Embedded TrueType Font", so that the original font can be displayed on a computer without the font installed, and there will be no garbled characters.
