Resource compiler and IPF compiler refer to the COUNTRY.SYS file which exists in the \OS2\SYSTEM directory. Since current SBCS OS/2 Warp's COUNTRY.SYS does not contain the latest code page information of DBCS NLVs, you'll need to replace the file with that of the target OS/2 Warp NLV. That is, if you'd like to compile an IPF file written in Hanguel, you need the COUNTRY.SYS file of OS/2 Warp H. The exception is Japanese whose code page information is already contained in the SBCS Warp's COUNTRY.SYS.
APSYMBOL.APS file, which defines symbols used in IPF source files, need to be replaced with the appropriate file. For Japanese, APSYM932.APS file in the IBM Visual Age C++ for OS/2 can be used, but for the other DBCS countries, you'll need to copy the files from each toolkit (Refer to IPFC (Information Presentation Facility Compiler)).
