[icu-design] updated proposal for encoding selection API

[Mohamed E. <el...@go...>]

Hello ICU design,
 This is an updated proposal to the API of encoding selection. The original
API was sent earlier by Mark Davis.
Please find the new API here...

http://bugs.icu-project.org/trac/browser/icu/branches/eldawy/6453/source/common/unicode/ucnvsel.h

there are small changes to function names, and ucnvsel_open( ) now takes
encoding names rather than converter lists.

Please review if you are interested.

Thanks,
 Mohamed
