[icu-design] ICU API proposal: API for "is this a right-to-left script"

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

Dear ICU team & users,

I would like to propose the following API for: *ICU 50*
Please provide feedback by: next *Tuesday, 2012-05-29*
Designated API reviewer: *Mark*
Ticket: http://bugs.icu-project.org/trac/ticket/7016

I propose to add the following:

C API (common, uscript.h):

U_DRAFT UBool U_EXPORT2
uscript_isRightToLeft(UScriptCode sc);

Java API (com.ibm.icu.lang.UScript):

static boolean isRightToLeft(int sc);

These would return TRUE for USCRIPT_ARABIC and USCRIPT_THAANA and FALSE for
USCRIPT_LATIN and USCRIPT_HANGUL, etc.

Sincerely,
markus
