[Talk-GB] Map layer with OS Locator comparison from ITO - apostrophes

I am sorry to reopen this topic but I think it would be a good idea to reconsider
the checking of punctuation in the OS Locator tiles.

Look at central Exeter for example:
<http://oscompare.raggedred.net/?zoom=15&lat=50.72407&lon=-3.52609&layers=B0TF>

Three-quarters of the differences reported here are in the presence or absence
of a single apostrophe.  This masks the more important discrepancies and makes
the report less useful.

I know that in principle, apostrophe differences can be resurveyed, tracked
down, investigated with phone calls to the council's naming department, etc.
But in practice many mappers will prefer to concentrate on substantial
differences and missing streets, considering punctuation less important.

Perhaps, then, a set of tiles can be produced which strips punctuation from
both the OSM and OS names before comparing?  This would clearly flag up the
things which need more urgent checking.
