Content Dictionaries
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

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:
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.

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

Warning
These text files contain terms that some persons may consider obscene, indecent or offensive. If you
import terms from these files into your content dictionaries, the terms will be displayed when you
later view the content dictionaries you have configured on the appliance.
