Editing Letter case (section)

Similar orthographic and graphostylistic conventions are used for emphasis or following language-specific or other rules, including:
* [[Font]] effects such as [[italic type]] or [[oblique type]], [[boldface]], and choice of [[serif]] vs. [[sans-serif]].
* In [[mathematical notation]] lower-case and upper-case letters have generally different meanings, and other meanings can be implied by the use of other [[typeface]]s, such as [[boldface]], [[fraktur]], [[script typeface]], and [[blackboard bold]].
* Some letters of the [[Arabic alphabet|Arabic]] and [[Hebrew alphabet]]s and some [[Hangul consonant and vowel tables|jamo]] of the Korean [[hangul]] have different forms depending on placement within a word, but these rules are strict and the different forms cannot be used for emphasis.
**In the Arabic and Arabic-based alphabets, letters in a word are connected, except for several that cannot connect to the following letter. Letters may have distinct forms depending on whether they are initial (connected only to the following letter), medial (connected to both neighboring letters), final (connected only to the preceding letter), or isolated (connected to neither a preceding nor a following letter).
**In the Hebrew alphabet, five letters have a distinct form (see [[Final form]]) that is used when they are word-final.
* In [[Georgian alphabet|Georgian]], some authors use isolated letters from the ancient [[Asomtavruli]] alphabet within a text otherwise written in the modern [[Georgian alphabet#Mkhedruli|Mkhedruli]] in a fashion that is reminiscent of the usage of upper-case letters in the Latin, Greek, and Cyrillic alphabets.
* In the [[Japanese writing system]], an author has the option of switching between [[kanji]], [[hiragana]], [[katakana]], and [[rōmaji]]. In particular, every hiragana character has an equivalent katakana character, and vice versa. Romanised Japanese sometimes uses lowercase letters to represent words that would be written in hiragana, and uppercase letters to represent words that would be written in katakana. Some kana characters are written in smaller type when they modify or combine with the preceding sign (''[[yōon]]'') or the following sign (''[[sokuon]]'').
