Syntax: standard IANA character set (charset) name
This sets the charset for storing page text in the database during
walks. Pages will be translated to this charset when inserted. If a
page cannot be translated, it is stored and labeled with its source
charset (if known). If left empty (the default) it is UTF-8.
This charset should be a superset of US-ASCII (same 7-bit
sequences), and translatable by the Search Appliance from all walked pages'
source charsets.
Note that this is not necessarily the charset that search
results will be displayed in: see Display Charset under Search
Settings. This setting is the default value for Display Charset; see
notes under Display Charset.
