LocalizedFontProcessor Class (Microsoft.Xna.Framework.Content.Pipeline.Processors)

Custom processor extends the SpriteFont build process to scan over the resource strings used by the game, automatically adding whatever characters it finds in them to the font. This makes sure the game will always have all the characters it needs, no matter what languages it is localized into, while still producing an efficient font that does not waste space on unnecessary characters. This is especially useful for languages such as Japanese and Korean, which have potentially thousands of different characters, although games typically only use a small fraction of these. Building only the characters we need is far more efficient than if we tried to include the entire CJK character region.
