Editing Capitalization (section)

===Digraphs and ligatures===
Some languages treat certain [[digraph (orthography)|digraph]]s as single letters for the purpose of collation. In general, where one such is formed as a [[ligature (typography)|ligature]], the corresponding uppercase form is used in capitalization; where it is written as two separate characters, only the first will be capitalized. Thus ''[[Oedipus]]'' or ''Œdipus'' are both correct, but ''OEdipus'' is not. Examples with ligature include {{lang|da|[[Ærøskøbing]]}} in [[Danish language|Danish]], where ''[[Æ|Æ/æ]]'' is a completely separate letter rather than merely a [[typography|typographic]] ligature (the same applies in Icelandic); examples with separate characters are {{lang|cy|[[Llanelli]]}} in [[Welsh language|Welsh]], where ''[[Ll]]'' is a single letter; and {{lang|cy|Ffrangeg}} in Welsh where ''[[ff (digraph)|Ff]]'' is equivalent to English ''F'' (whereas Welsh ''F'' corresponds to English ''V'').<ref>Lewis, H (ed) ''Collins-Spurrell Welsh Dictionary'' Collins UK 1977 p. 10. {{ISBN|0-00-433402-7}}</ref> Presentation forms, however, can use doubled capitals, such as the logo of the [[National Library of Wales]] ({{lang|cy|Llyfrgell Genedlaethol Cymru}}). The position in Hungarian is similar to the latter.
* An exception is the [[Dutch language|Dutch]] digraph ''[[IJ (letter)|IJ]]''. Both letters are capitalized even though they are printed separately when using a computer, as in {{lang|nl|[[IJsselmeer]]}}. In the past the digraph was written as ''[[Y]]'', and this still survives in some surnames.
* A converse exception exists in the [[Croatian alphabet]], where digraph letters ([[Dž]], [[Lj (letter)|Lj]], [[Nj (letter)|Nj]]) have mixed-case forms even when written as ligatures.<ref>Vladimir Anić, Josip Silić: "Pravopisni priručnik hrvatskog ili srpskog jezika", [[Zagreb]], 1986 (trans. ''Spelling handbook of [[Croato-Serbian language]]'')</ref> With [[typewriter]]s and [[computer]]s, these "title-case" forms have become less common than 2-character equivalents; nevertheless they can be represented as single title-case characters in Unicode (ǅ, ǈ, ǋ).
* In [[Czech language|Czech]] the [[Ch (digraph)|digraph ch]] (usually considered as a single letter) can be capitalized in two ways: Ch or CH. In general only the first part is capitalized (Ch), unless the whole text is written in capital letters (then it is written CH). In acronyms both parts are usually capitalized, such as VŠCHT for ''Vysoká škola chemicko-technologická'' ([[University of Chemistry and Technology, Prague|University of Chemistry and Technology]]). However, the practice is not unified when writing initial letters of [[personal name]]s (first name and surname), for example ''Jan Chudoba'' can be abbreviated both ''J.&nbsp;Ch.'' or ''J.&nbsp;CH.''<ref>{{cite journal |date=2000 |title=Z dopisů jazykové poradně |url=http://nase-rec.ujc.cas.cz/archiv.php?art=8187 |journal=Naše řeč |volume=83 |issue=4 |pages=223–224 }}</ref>
