Word document open handout can't show math symbols how do I convert symbols? Or another workaround is a problem with the Formula editor font. Open the document and double-click the math formula that shows the problem, and the formula Editor starts automatically. Click Style-Definition in the Equation Editor's interface, and in the Definition Style dialog box that pops up, select Advanced.
You can see the formula Editor's settings for fonts, paying special attention to the "variables" and "lowercase Greek alphabet" and "symbols" of these three items, if this is not supported by your system fonts, then the formula Editor does not correctly display the mathematical formula, You can select the fonts that you like in the corresponding Drop-down list box that you have installed on your system, and then enter the formula to display correctly when you set it up. The recommended variable uses the "Times New Roman" font, the lowercase Greek alphabet and the Fuhang are "Symbol" fonts, which are typically installed by the Windows system by default.
See in Word is garbled, but after entering the formula editor to see is the correct display of the formula, exit Formula Editor and then become garbled. In fact, this is because the formula in the Formula Editor is automatically displayed with the fonts supported by your system. But it hasn't been updated in the Word document, so you just need to click "File--update document ..." in the Equation Editor or press the shortcut key "Ctrl+s" to update the formula font to the document. After exiting, you can see that the formula has been displayed normally.
