Testing a Non-English Keyword
Open the New Keyword dialog and define the tested keyword.
To test a non-English language keyword do the following:
1.
Enter the search expression in Keyword.
2.
Enter or browse to the file containing the non‐English language content used to test the
keyword.
3.
Click Load.
Text appears in the Text pane.
4.
If text is incorrectly rendered, select other code sheets until the text is rendered correctly.
When a selected encoding is not one that was selected when the keyword was defined,
the Expression field contains this message: Wrong codepage for this expression.
5.
Click Hex to view content in hexadecimal. The values
x\ FFx\EE
in the file header
indicates that Unicode is the correct encoding. You may want to redefine the encoding
used for this keyword.
The hex representation of the underlying text appears.
6.
Test the keyword and click OK.

Viewing Unicode Files
By default, EnCase displays characters in ANSI (8‐bit) format on the Text and Hex tabs in
Courier New font. Viewing Unicode files properly requires modifications to both the formatting
and the font. First, the file or document must be identified as Unicode. This is not always
straightforward.
Text files (.txt) containing Unicode begin with a Unicode hex signature \xFF\xFE. Word
processor documents written in Unicode, however, are not so easy to identify. Typically, word
processor applications have signatures specific to the document, making identification of the file
as Unicode more difficult.

To view Unicode files do the following:
1.
Click Text Styles.
The Text Styles tab appears in the Filter pane. Notice the default characters between the
ASCII characters. The second eight bits of the 16‐bit Unicode encoding cannot be
translated.
2.
Click the desired Unicode‐based text style.
The text displayed in the Text or Hex tab is updated to reflect the new encoding.

Viewing Non-Unicode Files
Display a file in any encoding or code page after you define it.
To view non‐Unicode files:
1.
Click Text Styles with the text displayed in the Text or Hex tab of the View pane.
The Text Styles pane appears in the Filter pane.
2.
Click the desired non‐Unicode based text style.
The displayed text in the Text or Hex tab updates to reflect the new encoding.
Associating Code Pages
Non‐English language files can be associated with a particular code page. A code page list is
checked to prevent usage of an unavailable code page (if, for instance, a file is open on one
system, then reopened on another that does not have the complete set).
If an original code page is unavailable when a file is opened, the code page association is
removed. While this process is transparent, if you do open a case or mount a volume with a
missing code page, a message listing the missing code pages appears.
You can associate code pages manually or automatically through Windows identification.
To manually set the code page:
1.
Apply a Text Style with the desired code page to the entry.
2.
Check the code page check box on the EnCase main window.
To have Windows automatically associate code pages to entries:
1.
Select the Search button and check the Identify code page option.
2.
After the search completes, the code page column populates.
