The last two days have been drawing a completed map, using CAD very much, so always found some problems. Today, when I opened a drawing from someone else, I saw that there was still a bar symbol that could not be displayed ...
As with the solution to this problem, as far as I know, there are two ways:
First, replace the font used
First select the text that shows the disorder, and then press Ctrl + 1, the Mediation Properties dialog box to see the style of the text in the attribute, remembering the style. (In fact, this step can be omitted, directly into the next step, but sometimes in order to be able to modify the font file, you need to perform this step)
Then enter "ST" on the command line to open the Text Style dialog box. Find the text style that appears in the attribute. In the text list on the right, select the font you want to replace. (You can also see all the text styles and replace any font with exclamation marks)
After you have replaced the font you like, click "Apply", close the dialog box back to the CAD drawing interface, enter "re" to regenerate the graphics, you can see the font is all normal display. If the font is still not displayed properly, then only the appropriate font is installed. (see Second, install font files)

Second, install font files
This method is the simplest, the rough, searches the search engine the CAD font, and downloads. It is then copied to the CAD font directory, and some fonts need to be copied to the Windows directory.
