Displaying and Searching Diacritics and Special Characters
Although there are no non-Roman characters in LC authority records, users still want to adjust their browsers in order to display all diacritics and special characters in authority records. Authority records for items in most languages will display correctly without changing any settings in your preferred Web browser. The instructions below may be helpful if you want to view authority records containing diacritics and special characters.
Instructions for Windows
the Unicode Font in Windows XP
If you are using Microsoft Windows XP, the "universal
font" for Unicode should be automatically installed.
Arial Unicode MS font is a "full Unicode font"
-- it contains all of the characters, ideographs, and symbols defined
in the Unicode 2.1
* Unicode is a character
encoding standard developed by the Unicode Consortium. By using
more than one byte to represent each character, Unicode enables
almost all of the written languages in the world to be represented
by using a single character set.
If the "universal font" is not visible (i.e., you cannot see diacritics and special
characters), you will need to set the Latin-based font to Arial
Unicode MS (if it is not available on your system, you
may need to install it -- it will be called "Universal Font" on
the installation disks.)

Displaying Diacritics and Special Characters in Web Browsers
Setting up the browser to display diacritics and special characters is a 2-step
process. Begin by setting the default font to Arial
To set the font in Internet Explorer, from the Tools pulldown
- Select Internet Options --> Fonts
- Select "Latin based" from the Language script: menu
- Select "Arial Unicode MS" from the Web page
- Select "OK" to save the change.

When viewing catalog records, you will also need to make
sure that the character encoding for the page you are looking at
is set to Unicode (UTF-8). Often, the browser
sets the encoding automatically. You may
also have to choose the setting yourself, and this setting doesn't
always "stick" (so you may have to reset it).
To set UTF-8 encoding in Internet Explorer...
from the View pulldown menu
select Encoding > Unicode (UTF-8)
Also, make sure that Auto-Select is
unmarked. Please note, if "Unicode (UTF-8) is not currently displaying
in your Encoding menu, select "More" to find it.
To set UTF-8 encoding in Firefox... from the View pulldown
select Character Encoding -->Unicode (UTF-8).
In this case, you can set the Auto-Detect option to "Universal." Please
note, if "Unicode
(UTF-8)" is not currently displaying in your Character
Installing IMEs for Entering Non-Roman
Because there are currently no non-Roman characters in the Library of Congress Authorities catalog, users may not need to install the IMEs (Input Method Editors) in order to search and display non-Roman characters. If you wish to install IMEs, please view the help screen on installing IMEs in the Online Catalog help areas.
More on Displaying Diacritics and Special Characters on Macintosh Computers
This information comes from the Unicode Web site:
On Mac OS X, the Safari Web browser includes Unicode
support as does OmniWeb. OmniWeb,
however, does not currently provide support for all of Unicode
(it can, however,
take advantage of Unicode fonts for Windows if properly installed).
There are currently no Web browsers which provide direct Unicode
drawing (font support) on the Mac OS 9.x or earlier. All the browsers
use Apple Language Kits and WorldScript to varying degrees to support
and international text.
Language Kits are installed using your Mac OS 9.x installation
CD. Launch the Mac OS Install application. Proceed through the
initial screens, selecting the appropriate boot disk. When you
reach the "Install Software" screen, click on the "Customize" button.
This opens up the Custom Installation and Removal dialog box.
Scroll down to "Language Kits." Click on the check box,
and then select "Customized Installation" from the installation
popup to the right. (It will say "None selected" at first.)
This brings up a dialog box with a list of all the available language
kits. Select the ones you want, or use the menu at the top of the
dialog box to select all of them. Proceed with the installation.
If you already have Mac OS 9.0 installed, you will be asked if
you want to add or remove software after you select the installation
disk. Click on the "Add/Remove" button. This will bring
you to the Custom Installation and Removal dialog box.
The installation procedure is the same for Mac OS 8.6, except
that you will be installing "Multilingual Internet Access" instead
of Language Kits. For Mac OS 8.5.5 and earlier, it will be necessary
to purchase the individual language kits.
