Base: revert to using ASCII chararacters for imperial lengths

The new unit schema management is using U+2032 and U+2033 characters
for feet and inches while parser is expecting only ' and ", while
U+2032 and U+2033 are used for arcminute and arcsecond.

While this is not an ideal solution and parser should deal with both,
revert back to ASCII for now.
