Why does the CAD interface show a question mark garbled

Have you ever encountered an AutoCAD interface showing "?" Problem? This is caused by input method settings!

I encountered this problem a few days ago, according to my experience in using AutoCAD, generally encountered this problem is the reason for the font mismatch, please join me to analyze and solve this problem.

This is a rare case in which the following figure shows "?" in the CAD taskbar and in the Pop-up Options dialog box.

Recall yesterday, the use of normal, yesterday to find this problem between, due to the computer virus, it ghost a previous operating system. After that is installed a number of commonly used software, there is no big comparison of the wrong operation AH. Because I have done this many times, the problem should not be here. Is there a virus, the idea of a virus is a bit uncomfortable, but I have regained the system and kill the poison, should not have it.

is the AutoCAD environment variable in mischief? Can I configure the AutoCAD environment variables, accidentally touched what variables (because I have to reinstall the AutoCAD after the reconfiguration), but I have been operating for four years, should not appear this problem, but I still do not trust, The AutoCAD in the configuration file to reload the side, the problem is not resolved.

Excluding the above two reasons, I began to guess whether the system is set up a problem, it is the reason for input method. To get some clues, open the Control Panel, double-click Regional Options to pop up the Regional Options window and switch to the General tab, and you'll see "English (USA)" in "Your locale (location)" and change it to "Chinese (Chinese)", and clicking OK Open AutoCAD again, the problem is solved. Let the author a false alarm.

Originally, I want to look at the time of each time zone, in the area option in the General tab, the "Your Regional Settings (location)" changed to "English (United States)", resulting in the AutoCAD interface appeared "?".
