Note
Dictionaries containing non-ASCII characters may or may not display properly in
the CLI on your terminal. The best way to view and change dictionaries that
contain non-ASCII characters is to export the dictionary to a text file, edit that text
file, and then import the new file back into the appliance. For more information,

Word Boundaries and Double-byte Character Sets
In some languages (double-byte character sets), the concepts of a word or word
boundary, or case do not exist. Complex regular expressions that depend on
concepts like what is or is not a character that would compose a word (represented
as “\w” in regex syntax) cause problems when the locale is unknown or if the
encoding is not known for certain. For that reason, you may want to disable
word-boundary enforcement.

Importing and Exporting Dictionaries as Text Files
The content dictionary feature also includes, by default, the following text files
located in the configuration directory of the appliance:
located in the configuration directory of the appliance:
•
config.dtd
•
profanity.txt
•
proprietary_content.txt
•
sexual_content.txt
These text files are intended to be used in conjunction with the content
dictionaries feature to aid you in creating new dictionaries. These content
dictionaries are weighted and use smart identifiers to better detect patterns in data
and trigger filters when the patterns indicate compliance issues.

for more information accessing on
the configuration directory.
You can also create your own dictionary files and import them onto the appliance.
The best way to add non-ASCII characters to dictionaries is to add the terms into
the dictionary in a text file off the appliance, move that file onto the appliance,
and then import that file as a new dictionary. For more information about
importing dictionaries, see
