Orthotypographic fixes
Orthotypographic fixes

- use true apostrophes (’) instead of right quotes (')
- use a true (non‑breaking) hyphen instead of dash (demi‑minute)
- use a non‑breaking space before colons ( :)
- use non‐breaking spaces in dates (14 février 2020)
- use a non‑breaking space between a number and what it quantifies (4 ans)
- use a thin space (which is non‑breakable by default) between a number and its unit symbol (e.g. for currency: 100 €)
- use a thin space (which is non‑breakable by default) as the thousands separator (8 848 m)
- don’t use a capital letter for units (Octet → octet)
- add time formats, with correct mix of non-breaking and thin spaces
- human decimal units are variable if >= 2 (except mille), so use “(s)” — this is ugly, but I don’t know if we can use multiple formats…
