Code page
A list of characters which forms the character set for one or more languages. A code which is
unique within this code page is assigned to each of the characters in the list.
All of the code pages used in Windows share the ASCII range (codes 0 to 127).
A distinction is made between single-byte code pages and multiple-byte code pages.
In single-byte code pages (all European languages), each character is represented with a
single byte. Accordingly, single-byte code pages comprise a maximum of 256 characters.
Multiple-byte code pages (Asian languages) contain both characters which are stored as a
single byte and characters which are stored with two (or more) bytes. The shared ASCII
range is contained as a range of single-byte characters.
There is a 1:1 assignment between Windows code page and language family.
The language families are listed in Section "Language families".
Diacritical characters
(diacritical = distinguishing)
In most cases, a relatively small supplementary character, which is attached to a letter to
give the letter a specific stress, a specific pronunciation or even a new meaning.
Section "Special characters in different language families" contains a list of diacritical
characters.
If the combination of basic letters and diacritical characters belongs in a language-specific
alphabet, this combination is contained in the appropriate Windows character sets (code
page, Unicode) as a separate character.
Use of diacritical characters
A diacritical character is used
• To designate the combined character (e.g., Ģ = G cedilla, Õ = O tilde),
• For the combined input, if there is no separate key that possesses the required combined
• In Vietnamese and Thai, for normal coding in text files,
• For output (only in typographically compound texts): Diacritical characters and basic letter
In all the other cases, the combined letter is always considered as a compound unit.
In some cases, however, the combined letter is incorrectly referred to as the diacritical
character.
8
character
(see Section "Using a different keyboard assignment"),
are output separately, meaning that any combinations are possible, e.g., for ancient
languages and phonetics.
