Why does the CAD drawing not prompt the lack of font, and the font of the exclamation mark cannot be seen in the text style, and the text still shows the question mark after opening the drawing? As shown in the figure below.
First of all, let's talk about the picture above, the text above is a multi-line text, the text below is a single line of text, all of which are in the Standard text style, only using a small font txt.shx, and not checking [Use large font].
When large font is not checked, if it is a multi-line text, Chinese will automatically use Songti. As shown in the figure below
The single-line text all uses the txt.shx font, if the font does not support Chinese, then the Chinese part of the single-line text will display a question mark.
When encountering such problems, we can check [Use large font] in the text style. As shown in the figure below
After checking the box, double-click on the single line of text,?? to display it as Chinese characters. As shown in the figure below
