datawindow The importance of using fonts correctly in

        datawindow Interface design , Many people ignore font choices , Field to DW Went on , Let it go , The default is Arial typeface , I will not adjust it . If it is in English , It doesn't matter , But if there is Chinese in the content , That's a big difference , At this time, you should choose the appropriate Chinese font . Here is an analysis of the difference .

        The first is to open the experience , That's a simple one DW, The first column uses Arial typeface , There is obvious hysteresis when opening , If it is changed to Song typeface , There is almost no pause , When opened, the thread is generally smooth .

        Next , Test generation PDF（ Actually show 、 The same goes for printing ）. Generated PDF The effect is as follows ：

        This is to track the creation of fonts , It can be seen from it that ,Microsoft Sans Serif I don't use this font at all , But it was chosen 14000 many times . What is the concept ？ actually , The operating system is right c:\windows\fonts\micross.ttf This font file opens 14000 many times , And look for those Chinese fonts , All failed .

        that , Let's choose Song typeface ：

        Because the Chinese font is used to display Chinese , Only fonts were created in total 5 Time , That is to complete the required task .

        so , How important it is to use Chinese fonts correctly to display Chinese , There is a huge difference in efficiency .

Cause analysis ： Why is there such a big difference ？

        The font file actually defines the font for each character to be displayed , It can be understood as every character （ Including Chinese characters ） All have corresponding codes , And according to these codes , There is a corresponding definition similar to the picture . English usually uses upper and lower case letters with symbols , Probably 126 individual ,ASCII Encoding in 0-126 Between , There are tens of thousands of Chinese . So the English font is usually very small , The Chinese font is much larger . When using English Fonts , Those Chinese character codes , There must be no corresponding font in the English font , It must not be able to display Chinese characters . At this time, in order to display the Chinese characters , The bottom layer of a smart operating system will intelligently adapt to the appropriate font , So that the content can be displayed . And this adaptation process , It's a process of searching and trying , Less content , Efficiency has little effect , If there is more content , Then the efficiency will be greatly affected .

Conclusion ：

        Datawindow In design , Display Chinese fields , Be sure to use fonts that exist on your computer . If you use a font that doesn't exist , Your own application should have a font , The application completes the in-process installation of fonts , So as to improve the display and printing efficiency .
