with comma), incorrectly implemented as Ş (U+015E, S with cedilla) ș (U+0219, s with comma), incorrectly implemented as ş (U+015F, s with cedilla) Ț (U+021A, T with comma), incorrectly implemented as Ţ (U+0162, T with cedilla) ț (U+021B, t with comma), incorrectly implemented as ţ (U+0163, t with cedilla) The cedilla-versions of the characters do not exist in the Romanian language (they came to be used due to a historic bug). The UCS now says that encoding this was a mistake because it messed up Romanian data and the letters with cedilla and the letters with comma are the same letter with a different style. Since Romanian hardware keyboards are not widely available, Cristian Secară has created a driver that allows Romanian characters to be generated with a US-style keyboard in all versions of Windows prior to Vista through the use of the AltGr key modifier. Windows Vista and newer versions include the correct diacritical signs in the default Romanian Keyboard layout. This layout has the Z and Y keys mapped like in English layouts and also includes characters like the 'at' (@) and dollar ($) signs, among others. The older cedilla-version layout is still included albeit as the 'Legacy' layout. Slovak In Slovakia, similarly to the Czech Republic, both QWERTZ and QWERTY keyboard layouts are used. QWERTZ is the default keyboard layout for Slovak in Microsoft Windows. Spanish Spain The Spanish keyboard layout is used to write in Spanish and in other languages of Spain such as Catalan, Basque, Galician, Aragonese, Asturian and Occitan. It includes Ñ for Spanish, Asturian and Galician, the acute accent, the diaeresis, the inverted question and exclamation marks (¿, ¡), the superscripted o and a (º, ª) for writing abbreviated ordinal numbers in masculine and feminine in Spanish and Galician, and finally, some characters required only for typing Catalan and Occitan, namely Ç, the grave accent and the interpunct ( / , used in l·l, n·h, s·h; located at Shift-3). It can also be used to write other international characters, such as those using a circumflex accent (used in French and Portuguese among others) or a tilde (used in both Spanish and Portuguese), which are available as dead keys. However, it lacks two characters used in Asturian: Ḥ and Ḷ (historically, general support for these two has been poor – they aren't present in the ISO 8859-1 character encoding standard, or any other ISO/IEC
