The Solution of Mathematical Formulas and Symbols Displayed as garbled Codes
Many times, downloading math test papers and courseware from the internet can't display math formulas and symbols correctly on our computers, but we see some chaotic and strange symbols.
Actually, it has something to do with your system font. The test paper (or courseware) provider edits the test paper (or courseware) according to the font in its system, but the font file may not be installed in your system. At this time, because the system can't find this font file, it can only be displayed as some blank boxes or garbled codes, as shown in the above figure.
Generally speaking, there are not many font files for editing mathematical formulas, but even some commonly used font files may not be installed in your system due to system installation. You can download these commonly used mathematical font files from the fonts on the home page. After decompression, an "Installation Instructions" will appear. Txt ",which explains the installation method of font file in detail (if the installation program has not changed after running, please try to install it manually according to the instructions). In general, as long as the font file is installed, you can see that the formula display is no longer garbled.
If the font file still can't solve the problem after installation (there is no problem with the display of general mathematical symbols, but the formula edited by the formula editor is still displayed as garbled), it is necessary to check whether there is any problem with the setting of mathematical fonts in your formula editor. First, open the test paper (or courseware), double-click the mathematical formula that shows the question, and then the formula editor will start automatically. Click Style-Definition in the Formula Editor interface, and click Advanced in the pop-up Define Style dialog box. At this time, you can see the font settings of the formula editor, paying special attention to the settings of variables, lowercase Greek letters and symbols. If your system does not support this font, the formula editor cannot display the mathematical formula correctly. The easiest way is. Of course, you can also select the font you like and install in your system in the corresponding drop-down list box, so that it can be displayed correctly after setting and entering the formula. It is suggested to use "Times New Roman" font for variables and "symbol" font for lowercase Greek letters and symbols. Generally speaking, these two fonts are installed by default in windows system (I have also encountered unsigned fonts in the school printing room, which is a bit incredible. )。 There are these necessary fonts in the font download of my homepage, but there is no times new roman font, because I have never met a computer without this font, hehe.
Sometimes what you see in Word is garbled, but what you see after entering the formula editor is the correctly displayed formula, and then it becomes garbled after exiting the formula editor. In fact, this is because the formula is automatically displayed in the formula editor in the font supported by your system, but it is not updated in the word document. At this time, you only need to click "File-Update Document ..." or press the shortcut key "Ctrl+S" in the formula editor to update the formula font into the document. After exiting, you can see that the formula has been displayed normally.
