The system provides DBCS font files.
DBCS font files are physical files that contain frequently used double-byte characters. When using the character generator utility, you can use the characters in these files as the base for a new user-defined character. These files are supplied with read-only authority as they are not to be changed. If you do not use character generator utility or the Advanced DBCS Printer Support licensed program, you can delete these files to save space. They all exist in the QSYS library.
The following DBCS font files are distributed with the DBCS national language versions of the i5/OS™ licensed program. They are used as a reference for the character generator utility (CGU) and the Advanced DBCS Printer Support licensed program.
