Solved the problem that cewolf is displayed as a box in Chinese in linux.

Solved the problem of cewolf displaying the box in Chinese in linux-Linux general technology-Linux technology and application information. The following is a detailed description. The server uses Ubuntu. In order to facilitate command line management, it sets a full English environment. Today, when I deployed the module that generated the graph to the server, I found that Chinese characters were displayed as boxes. I searched for a long time from google and did not come up with a reason. Some of the articles found are about encoding settings. I am not doing this. Because I am using UTF-8 code throughout the development process, there is no reason in my workstation display normal and not on the server. Later, I occasionally found an article about the deployment of Solaris, which may be the reason why jre cannot find the Chinese font. At first glance, I did not copy the Chinese font in the jre on the server, and the text cannot be displayed normally without it.

The simplest solution is to create a fallback folder in the $ JAVA_HOME/jre/lib/fonts directory and put the Chinese font in the folder, such as simsun. ttf.

Many JFreeChart programs developed on windows are deployed on linux servers and cannot correctly display Chinese characters. If all the codes are unified: for example, if UTF-8 is used, this problem may also occur when the Linux workstation is deployed to the server. Because the graphic interface is usually not installed when the server is installed, the Chinese language will not be considered too much, just as I forgot to install it.
