Error description
Unicode Services conversion for bidirectional code pages always goes through a two stage process, converting characters from the source code page to Unicode, and then from the intermediate Unicode representation to the target code page values. In the context of this indirect conversion, the Language Environment iconv logic sends the wrong code page name to the layout service routine, incorrectly passing the name of the intermediate code page. As a result, the service routine fails to recognize that the conversion string is a candidate for layout transformation, and iconv does not process any layout values

Problem summary
**************************************************************** * USERS AFFECTED: Language Environment C/C++ applications * * that use iconv interfaces with Bidi * * layout transformations. * **************************************************************** * PROBLEM DESCRIPTION: In the iconv_open() interface, * * internal logic that evaluates whether * * to initialize Bidi layout services is * * incorrect. As a result, iconv_open() * * fails to recognize Bidi conversions * * and does not set up data structures * * for layout transformations when they * * are needed. * * * * Testing of this APAR exposed a second * * problem. An out-of-bounds reference * * to an internal layout buffer causes * * unexpected results, including the * * possibility of an 0C4 abend during * * layout transformation. * **************************************************************** * RECOMMENDATION: * **************************************************************** See Problem Description.
Problem conclusion
Logic in the iconv_open() interface has been corrected so that Bidi conversions are now recognized and the appropriate layout initialization takes place. The internal layout buffer is now allocated dynamically to avoid out-of-bounds references during layout transformation.
