Language family
A language family is a group of languages which uses the same code page. This requires
the use of the same basic alphabet (e.g., Latin or Cyrillic), but it does not mean that the
alphabet of all languages of this group is the same.
There is a 1:1 assignment between Windows code page and language family.
The language families are listed in Section "Language families".
Font files (TrueType fonts)
Windows XP does not use font files that are stored separated for each code page; instead
it uses something known as "Big Fonts", which are fonts that contain the character set for
several code pages. saving memory capacity for the common characters.
With Word 2003, the selection of characters from this total character set is performed via the
Unicode coding, not via the code page coding. This makes it impossible to mix up characters
with the same code in different code pages.
Default language
The term "default language" is used in this guide for the language of the operating system,
i.e., German for a German Windows environment and English for an English Windows
environment.
Default keyboard setting
Under "Control Panel" → "Regional and Language Options", in the tab "Languages", click
under the heading "Text Services and Input languages" on the button "Details..." to reach the
dialog box "Text Services and Input languages".
Here you can see the default keyboard setting in the "Settings" tab under the heading
"Default Language and Region Support".
The default keyboard setting consists of a language property (left) and a keyboard
assignment (right).
This language property of the default keyboard setting need not absolutely match the default
language.
Text file
The term "Text file" is used to describe a file which does not contain any formatting
(font type, font size, underscore, bold, italics etc.) or embedded objects (pictures, tables,
graphics, footnotes etc.).
This means that, apart from the text characters, the file will only contain ASCII control
characters like Tab, CR and LF (tab indent, carriage return and line feed).
The text characters are taken from a particular code page.
Occasionally, text files are also incorrectly referred to as ASCII files. This is only correct
if a text file only contains ASCII characters (codes 0 to 127) and is therefore code page
invariant.
Unicode
A 16-bit character set for which code pages are no longer required. All character codes are
unique, without needing to specify the code page. Unicode programs like Word 2003 do not
offer code page-dependent interpreting of characters and thus also cannot display
characters differently by assigning a font or language property.
