The Carnival of Vilanova i la Geltrú has documented history from 1790 and is one of the richest in the variety of its acts and rituals. It adopts an ancient style in which satire, the grotesque body (particularly cross-dressing and displays of exaggerated bellies, noses and phalli) and above all, active participation are valued over glamorous, media-friendly spectacles that Vilanovins mock as "thighs and feathers". It is best known for Les Comparses (held on Sunday), a tumultuous dance in which 12,000 or more dancers organized into rival groups throw 75 tons of hard candies at one other. The women protect their faces with Mantons de Manila (Manila shawls) but eye-patches and slings for broken arms are common the following week. Vilanovins organize an elaborate ritual for the arrival of King Carnival called l'Arrivo that changes every year. It includes a raucous procession of floats and dancers lampooning current events or public figures and a bitingly satiric sermon (el sermo) delivered by the King himself. On Dijous Gras, Vilanovin children are excused from school to participate in the Merengada, a day-long scene of eating and fighting with sticky, sweet meringue.

Several subsets of Unicode are standardized: Microsoft Windows since Windows NT 4.0 supports WGL-4 with 652 characters, which is considered to support all contemporary European languages using the Latin, Greek, or Cyrillic script. Other standardized subsets of Unicode include the Multilingual European Subsets: MES-1 (Latin scripts only, 335 characters), MES-2 (Latin, Greek and Cyrillic 1062 characters) and MES-3A & MES-3B (two larger subsets, not shown here). Note that MES-2 includes every character in MES-1 and WGL-4.

Ah, so.. WGL-4 with 652 characters

Honorary knighthoods are appointed to citizens of nations where Queen Elizabeth II is not Head of State, and may permit use of post-nominal letters but not the title of Sir or Dame. Occasionally honorary appointees are, incorrectly, referred to as Sir or Dame - Bill Gates or Bob Geldof, for example. Honorary appointees who later become a citizen of a Commonwealth realm can convert their appointment from honorary to substantive, then enjoy all privileges of membership of the order including use of the title of Sir and Dame for the senior two ranks of the Order. An example is Irish broadcaster Terry Wogan, who was appointed an honorary Knight Commander of the Order in 2005 and on successful application for dual British and Irish citizenship was made a substantive member and subsequently styled as "Sir Terry Wogan KBE".
