Elektra  0.9.3
Plugin: iconv

This plugin is a filter plugin that converts between different character encodings.

Consider a user insisting on a latin1 character encoding because of some old application. All other users already use, for example, UTF-8. For these users, the configuration files are encoded in UTF-8. So we need a solution for the user with latin1 to access the key database with proper encoding.

On the other hand, contemplate an XML file which requires a specific encoding. But the other key databases work well with the users encoding. So a quick fix for that backend is needed to feed that XML file with a different encoding.

The iconv plugin provides a solution for both scenarios. It converts between many available character encodings. With the plugin’s configuration the user can change the from and to encoding. The default values of the plugin configuration are: from encoding will be determined at run-time. to encoding is UTF-8.

Parameters:

Note that for writing the configuration from and to is swapped. A key database that requires a specific encoding can make use of it. To sum up, every user can select a different encoding, but the key databases are still properly encoded for anyone.

For example iconv/iconv.ini should be latin1, but all users have UTF-8 settings:

`` @section autotoc_md285 Mount the fileiconv/iconv.iniusing theiniplugin together withiconv` sudo kdb mount "$PWD/src/plugins/iconv/iconv/iconv.ini" system/tests/iconv ini iconv from=UTF-8,to=ISO-8859-1

Check the file type of the mounted file

file -b "`kdb file system/tests/iconv`" #> ISO-8859 text

kdb get system/tests/iconv/a # converts ISO-8859 to UTF-8 #> hellö

kdb set system/tests/iconv/a öäß # converts UTF-8 to ISO-8859 kdb get system/tests/iconv/a #> öäß

Cleanup

kdb set system/tests/iconv/a hellö sudo kdb umount system/tests/iconv ```
