[icu-design] ICU4C API proposal: U8_NEXT etc.: handle NUL-terminated strings

[Markus S. <mar...@gm...>]

Dear ICU team & users,

I would like to propose the following API for: *ICU 51*
Please provide feedback by: next *Tuesday, 2012-10-23*
Designated API reviewer: *Andy*
Ticket: http://bugs.icu-project.org/trac/ticket/9664

Many ICU API functions take a string length of -1 to mean that the input
string is NUL-terminated. In the implementation, it would be convenient if
we could use that directly in the U8_NEXT(), U8_GET(), U16_NEXT() and
U16_GET() "safe" macros.

I propose that we change these 4 macros accordingly, rather than
introducing new macros.

I propose that we implement the 2 just-proposed new macros
U8_NEXT_OR_FFFD() and U8_GET_OR_FFFD() in the same way. (Ticket
#9662<http://bugs.icu-project.org/trac/ticket/9662>
)

Sincerely,
markus
