Fontconfigand the core X Fonts system. The newer
Fontconfigfont subsystem simplifies font management and provides advanced display features, such as anti-aliasing. This system is used automatically for modern applications developed using the (Qt 3) or (GTK+ 2) graphical toolkits. For backward compatibility with older legacy X applications, Red Hat Enterprise Linux includes the original font subsystem, called the Core X Font subsystem. This system is provided through the X Font Server (xfs). The
xfsservice manages the look and scalability of older fonts within some X applications. Legacy fonts will be discussed later in this chapter.
xfsservice is configured to run by default in runlevels 2, 3, 4 and 5 and can be managed using initscript utilities such as chkconfig and the Services Configuration Tool (
system-config-services). The X Window System requires the
xfsservice in order to run.
6.1. Adding new fonts for a user
~/.fonts/directory in the user's home directory. Use the
fc-cachecommand to update the font information cache, as in the following example:
fc-cachecan be obtained from the
- Double-click on the "Computer" icon on your desktop.
- In the "File" menu, choose "Open Location..."
- Type in:
- When the fonts window appears, drag and drop the fonts to be installed into this window.

- If it does not already exist, create a directory called
/usr/share/fonts/local/using the following command as root:
mkdir /usr/share/fonts/local/If creating the
/usr/share/fonts/local/directory is necessary, it must be added to the
xfspath using the following command as root:
chkfontpath --add /usr/share/fonts/local/
- Copy the new font file into the
- Update the font information by issuing the following command as root:
ttmkfdir -d /usr/share/fonts/local/ -o /usr/share/fonts/local/fonts.scale
- Reload the

Chapter 9. Advanced Topics
9.1. Using the
--outputoption. When doing conversions it is always a good idea to backup ones original files first.
- List character-set encoding names:
- Convert ISO8859-1 (legacy Western European) content to utf-8
iconv -f ISO_8859-1 -t UTF-8 oldfile > newfileIn the above example, the oldfile is encoded in ISO8859-1, while the "newfile" will be encoded in UTF-8.
- Similarly to convert EUCJP content to UTF-8
iconv -f EUCJP -t UTF-8 oldfile > newfile
9.2. Using the
convmvpackage to use this tool. The following are examples of options available using the
- List character-set encoding names:
convmvruns in test mode by default, one needs to use the
--notestoption for the changes to be actually effected.
- Convert ISO8859-1 (legacy Western European) filenames in directory DIR to UTF-8
convmv -f iso-8859-1 -t utf8 DIR
- Similarly, convert EUCJP filenames in DIR to UTF-8
convmv -f euc-jp -t utf8 DIR
