問題

• How do I change the character encoding to ISO-8859-15 (or any other encoding)?
• How to change the character encoding from UTF-8 to ISO-8859-1 ?

決議

Change the LANG environment variable to something suitable to you. For example, for ISO-8859-15 and French from France you would set it to "fr_FR.iso885915@euro". This can be set system-wide in /etc/sysconfig/i18n or per-user in the relevant shell startup file (~/.bashrc for example). To know what locales are available, run "locale -a -v".

ASCII is a seven-bit encoding technique which assigns a number  to  each of the 128 characters used most frequently in American  English.  This allows most computers to record and display basic text.  ASCII does  not include symbols frequently used in other countries, such  as the  British pound symbol or the German umlaut. ASCII is understood  by almost  all email and communications software.

ISO  8859 is an  eight-bit extension to ASCII developed by ISO (the  International  Organization for Standardization). ISO 8859 includes the  128 ASCII  characters along with an additional 128 characters, such as  the British  pound symbol and the American cent symbol. Several  variations of the ISO  8859 standard exist for different language  families:

• Steps to change the locale:

Raw

locale -a, --all-locales (Get locale-specific information. Write names  of available locales)

• Editing the configuration file:

Raw

vi /etc/sysconfig/i18n

• Change the following line where XX is your default language (US, AU, ZB):

Raw

LANG="en\_XX.UTF-8" to LANG="en\_XX.iso88951"

• Reboot your system as the changes can take effect.

根源

• By default, Red Hat Enterprise Linux uses UTF-8. In some cases, applications may need another encoding.

診斷步驟

• List available locales:

Raw

locale -a -v

• Example of /etc/sysconfig/i18n for a Belgian system using French and UTF-8:

Raw

LANG="fr_BE.utf8"  
SYSFONT="latarcyrheb-sun16"
