Solve spark garbled characters in Linux

Solve spark garbled characters:
In Linux, the problem of garbled Chinese characters in the Java graphic interface is often caused by the absence of appropriate fonts in the appropriate JRE/fonts.

 

For example, spark will ~ /. Write the last line in install4j, indicating that the JRE used by Spark is its own JRE.
Jre_version/home/gaoyibo/work/jdk1.6.0 _ 05 1 6 0 05
Jre_version/usr 1 6 0 0
Jre_version/home/gaoyibo/comodo/openfire/spark/JRE 1 6 0 02

Solve the garbled problem:

1. Find the JRE path and create the fallback folder.
Code: CD/home/gaoyibo/comodo/openfire/spark/JRE/lib/Fonts
Sudo mkdir fallback
2. Go to the fallback folder and link the Chinese font (I chose wenquanyi zhenghei)
Code: CD fallback
Sudo ln-S/usr/share/fonts/TrueType/wqy/wqy-zenhei.ttc
Sudo mkfontdir
Sudo mkfontscale
