Unreadable characters for non-latin locales [FS#4607]

	OpenTTD does not ship a non-latin font in its graphics files. As a

	result OpenTTD needs to acquire the font from somewhere else. What

	OpenTTD does is ask the operating system, or a system library, for

	the best font for a given language if the currently loaded font

	does not provide all characters of the chosen translation. This

	means that OpenTTD has no influence over the quality of the chosen

	font; it just does the best it can do.

	If the text is unreadable there are several steps that you can take

	to improve this. The first step is finding a good font and configure

	this in the configuration file. See section 9.0 of readme.txt for

	more information. You can also increase the font size to make the

	characters bigger and possible better readable.

	If the problem is with the clarity of the font you might want to

	enable anti-aliasing by setting the small_aa/medium_aa/large_aa

	settings to "true". However, anti-aliasing only works when a 32 bits

	blitter has been selected, e.g. blitter = "32bpp-anim", as with the

	8 bits blitter there are not enough colours to properly perform the

	anti-aliasing.
