For the ISO 8859–1 (Latin–1) encoding, used for Western European
languages, accented letters are included. Most ideographic characters, such
as used in Asian languages, are also considered letters.
Whatever the language and encoding used for a particular document (file or
email message), the system maps encoded characters to the Unicode 2.0
standard. The Unicode 2.0 standard is then used to determine if a given
character is a letter or a digit (or neither):
• A letter is any Unicode character in one of these Unicode categories:
Ll (lowercase letter), Lu (uppercase letter), Lt (titlecase letter),
Lm (modifier letter), or Lo (other letter).
• A digit is any Unicode character whose Unicode name contains the word
DIGIT , provided it is not in the range \u2000 (en quad = en space) through
\u2FFF (ideographic description – future).
Letters and digits in files
Although all letters and digits are word characters, their treatment in files
(including email message attachments) depends on the character encoding
used. You can search for any words in email message bodies and headers,
regardless of the encoding.
You can search for words in files (including email body, header, attachments,
and indexed documents) provided the character encoding is one the following:
• ISO-LATIN-1 • ISO-8859-1
•US-ASCII •UTF-8
• ISO-2022-JP • BIG5
• ISO-8859-2 • koi8-r
• EUC-KR • WINDOWS-1252
• WINDOWS-1253 • WINDOWS-1254
• WINDOWS-1255 • WINDOWS-1256
• gb2312 • WINDOWS-1258
