9247	locale - build failure with recommended icu configuration	hvemha@…	Artyom Beilis	"Configuring icu as recommended here:[[Br]]
http://source.icu-project.org/repos/icu/icu/trunk/readme.html#RecBuild
[[Br]]More precisely, build fails if icu::UnicodeString contructors are declared explicit.
The attach patch fixes build errors.

All fixes in formatter.cpp constructs UnicodeStrings from invariant strings (invariant characters defined here: http://icu-project.org/apiref/icu4c/platform_8h.html#a7fb0b0fede299f9d74973b15e79d3085). Previously all these constructors would involve an extra overhead as they were depending on the conversion framework.

The change in time_zone.cpp still depends on the conversion framework (behavior not changed). I do not think it is possible to guarantee that the provided string only includes invariant characters. In this case, the resulting string is undefined."	Bugs	new	To Be Determined	locale	Boost 1.55.0	Problem
