Move font selection to its own file
Browse files Browse the repository at this point in the history 
This was splitting up other MSS, and as its own file, it is much
easier for another project to change or reuse the file, either
adapting the font selection (e.g. for different Han unification
choices) or reusing our font selection work for their project.

About fonts:
Noto is a font family that wants to cover most of Unicode with a harmonic
design across various scripts. We use Noto for most text, with some support
for backward-compatibility and Unifont as fallback.
By order:
1. Noto Sans is available for most scripts and it is used as a first choice.
Where available the UI version of the fonts is used. In some cases the UI version
has fewer glyphs, so both are listed. Most of the list is in alphabetical order,
but there are some exceptions
- Noto Sans UI is before all other fonts
- The CJK fonts are manually ordered. The used CJK font covers all CJK
languages, but defaults to the japanese glyph style if various glyph
styles are available. (We have to default to one of JP, KR, SC, TC because
this carto style has no knowledge about what language the “names” tag
contains. As in Korea Han characters are not so widely used, it seems
better to default to either Chinese or Japanese. As Chinese exists in the
two variants SC/TC, it won’t be a uniform rendering anyway. So we default
to Japanese. However, this choise stays somewhat arbitrary and subjective.

2. Noto provides three variants of Arabic: Noto Kufi Arabic, Noto Naskh Arabic
and Noto Nastaliq Urdu. Naskh is the most commonly used style of Arabic.
Furthermore, Noto Naskh is the Arabic font of the Noto family with the greatest
coverage and the only one that has an UI variant. Therefor this style uses
Noto Naskh Arabic UI. The Arabic fonts are placed behind Sans fonts because
they might re-define some commonly used signs like parenthesis or quotation
marks, and the arabic design should not overwrite the standard design.
3. Noto provides two variants of Emoji: Noto Color Emoji and Noto Emoji. The
colour variant is a SVG flavoured OpenType font that contains coloured emojis.
This is not useful in cartography, so we use the “normal” monochromatic
Noto Emoji.
4. The list still includes DejaVu for compatibility on systems without Noto.
5. Unifont. This is a fallback of last resort with excellent coverage.
Unifont Medium covers the whole Unicode BMP without surrogates and without PUA.
Unifont Upper Medium covers some parts of the other Unicode planes. Unifont
Medium Sample would cover the BMP PUA with replacement characters, but cannot
be used because Mapnik does not support SBIT TTF.
