Is that me or I see 3 vertical dots in your last line (instead of 2
vertical dots for the usual colon) ? This unusual sign is certainly
NOT the one used to note scales on maps or ratios. We use and see the
2-dots colon almost always.

The 3-dots symbol (or punctuation) is clearly distinct, and not an
accident. It is very uncommon. It is not a duplicate encoding. May be
it is used for noting ratios (I've never seen that) or as
asupplementtary mathematical operator, or as a custom separator
similar in use to the vertical pipe in some contexts that require
several types of separators visually distinct.

Did you type the correct character ?
