i've picked up this kind of thousand separation at some point to make large numbers scannable. c.f. 1600000000 1'600'000'000 separating at 10³ is due to counting customs of the region i live in. using an apostrophe `U+0027` appears to be the least wrong use of possible glyphs accessible on my keyboard layout also c++14 does it this way
