Iconv for large files

Hi

I am using iconv command to convert the encoding of files.
Below is the command used:
Code:
iconv -f UCS-2 -t UTF-8 inputfile.txt> outputfile.txt

The command is working fine for files less than 2GB.
When I try converting the files of more than 2GB size I get an error as 'Can't open file'. I now understand that iconv will not be able to convert huge files.
I am using ksh shell
Can someone provide a solution to this.

Thank you in advance.
vrcr

NAME
iconv - Converts encoded characters to another codeset SYNOPSIS
iconv -f from_code -t to_code [file...] STANDARDS
Interfaces documented on this reference page conform to industry standards as follows: iconv: XCU5.0 Refer to the standards(5) reference page for more information about industry standards and associated tags. OPTIONS
Specifies the input codeset. Specifies the output codeset. OPERANDS
Specifies one or more files that contain the data to be converted. If this operand is omitted, the standard input is used. DESCRIPTION
The iconv command converts the encoding of characters in file from one coded character set to another and writes the results to standard output. The input and output coded character sets are identified by from_code and to_code. If the file operand is not specified on the command line, the iconv command reads the standard input. The result of specifying invalid characters in the input stream is that the input value is translated to the substitute character. [Tru64 UNIX] Current industry standards do not specify the name format, implementation, and location of the codeset converters used by this command. On this operating system, the command searches directories of algorithmic and table converters to find one that performs the requested conversion. The names of codeset converters adhere to the following format: fromcode_tocode EXIT STATUS
Success. An error occurred. ERRORS
[Tru64 UNIX] You can view the diagnostic messages that may be returned by the iconv command by entering the following commands: cd /usr/lib/nls/msg/en_US.ISO8859-1 dspcat iconv.cat EXAMPLES
The following examples use the iconv command: To convert the contents of the eucJP_data file from the eucJP to the SJIS codeset and save the results in the sjis_data file, enter: iconv -f eucJP -t SJIS eucJP_data > sjis_data To convert the contents of the eucJP_data file from the eucJP codeset to the UCS-4 codeset and save the results in the UCS_4_data file, enter: iconv -f eucJP -t UCS-4 eucJP_data > UCS_4_data ENVIRONMENT VARIABLES
The following environment variables (see i18n_intro(5) and l10n_intro(5)) affect the execution of the iconv command: Specifies a default value for the locale category variables that are not set. If set to a nonempty string value, overrides the values of all other locale variables, including LANG. Determines the locale for interpreting byte sequences as characters in, for example, command parameters. Spec- ifies the locale used to find translations, if any, for the command's message catalogs. [Tru64 UNIX] Specifies the search path used to find locales and the subdirectories that contain codeset converters. The default is /usr/lib/nls/loc. Determines the location of message catalogs for the processing of LC_MESSAGES. FILES
[Tru64 UNIX] Algorithmic converters. [Tru64 UNIX] Table converters. SEE ALSO
Commands: genxlt(1) Functions: iconv(3), iconv_close(3), iconv_open(3) Others: i18n_intro(5), iconv_intro(5), l10n_intro(5), standards(5) Writing Software for the International Market iconv(1)
