prevent C++ locale number formatting in text APIs (try 3)
This time it is the formatting of floating numbers in progress reporting with a radix charater potentially not being dot. Followup of 7303e11ff28f920a6277c159aa46f80c007350bb. Regression of b58e2c7c56b1416a343e81f9f80cb1f02c128e25 in so far as it exchanging very effected with slightly less effected code. LP: 1611010 (cherry picked from commit 0919f1df552ddf022ce4508cbf40e04eae5ef896)
