As briefly discussed in [[Unicode]] Technical Note #26,<ref>[http://www.unicode.org/notes/tn26/ Unicode Technical Note #26: On the Encoding of Latin, Greek, Cyrillic, and Han], retrievedHozzáférés ideje: April 23, 2007</ref> "In terms of implementation issues, any attempt at a unification of Latin, Greek, and Cyrillic would wreak havoc [and] make casing operations an unholy mess, in effect making all casing operations context sensitive [...]". In other words, while the shapes of letters like '''A''', '''B''', '''E''', '''H''', '''K''', '''M''', '''O''', '''P''', '''T''', '''X''', '''Y''' and so on are shared between the Latin, Greek, and Cyrillic alphabets (and small differences in their canonical forms may be considered to be of a merely [[Typography|typographical]] nature), it would still be problematic for a multilingual [[character set]] or a [[font]] to provide only a ''single'' [[codepoint]] for, say, uppercase letter '''B''', as this would make it quite difficult for a wordprocessor to change that single uppercase letter to one of the three different choices for the lower case letter, '''b''' (Latin), '''β''' (Greek), or '''в''' (Cyrillic). Without letter case, a 'unified European alphabet'—such as '''ABБCГDΔΕZЄЗFΦGHIИJ'''...'''Z''', with an appropriate subset for each language—is feasible; but considering letter case, it becomes very clear that these alphabets are rather distinct sets of symbols.
