== Character categories within scripts ==

Unicode provides a general category property for each character. So in addition to belonging to a script every character also has a general category. Typically scripts include letter characters including: uppercase letters, lowercase letter and modifier letters. Some characters are considered titlecase letters for a few [[Precomposed character|precomposed]] ligatures such as Dz (U+01F2). Such titlecase ligatures are all in the Latin and Greek scripts and are all [[Unicode compatibility characters |compatibility characters]], and therefore Unicode discourages their use by authors. It is unlikely that new titlecase letters will be added in the future.

Most writing systems do not differentiate between uppercase and lowercase letters. For those scripts all letters are categorized as "other letter" or "modifier letter". Ideographs such as Unihan ideographs are also categorized as "other letters". A few scripts do differentiate between uppercase and lowercase however: Latin, Cyrillic, Greek, Armenian, Georgian, and Deseret. Even for these scripts there are some letters that are neither uppercase nor lowercase.

Scripts can also contain any other general category character such as '''marks''' (diacritic and otherwise), '''numbers''' (numerals), '''punctuation''', '''separators''' (word separators such as spaces), '''symbols''' and non-graphical '''format''' characters. These are included in a particular script when they are unique to that script. Other such characters are generally unified and included in the punctuation or diacritic blocks. However, the bulk of characters in any script (other than the common and inherited scripts) are letters.
