FindFallbackFont()

bool Win32FontCacheFactory::FindFallbackFont ( const std::string & language_isocode, MissingGlyphSearcher * callback ) const

inlineoverridevirtual

We would like to have a fallback font as the current one doesn't contain all characters we need.

Parameters

language_isocode	The language, e.g. en_GB.
callback	The function to call to check for missing glyphs.

Returns

true if a font has been set, false otherwise.

Implements FontCacheFactory.
