Can some one please tell me how can i upload a file using BSP,read the file and convert the contents of file to unicode.
I am using simple HTML to upload the file that works fine. But my problem is.. the contents of the file are in some other language(Chinese) and i need to convert it to unicode. If i try to set the locale and read the file..it fails. Can someone please help me out.
Thanks....

well if you use the HTMLB tag to upload the data it will be returned as binary string. There is some good online help for the fileUpload tag that shows you how to do the data extraction part. You should then be able to convert the code page from the source one to a compatible destination one using some function calls. First call SCP_CODEPAGE_BY_EXTERNAL_NAME. With this you can convert the external name of the encoding type to the interal SAP code page.
call function 'SCP_CODEPAGE_BY_EXTERNAL_NAME'
exporting
external_name = encoding
* KIND = 'H'
importing
sap_codepage = codepage
exceptions
not_found = 1
others = 2.
Next you can call function SCP_TRANSLATE_CHARS to make the conversion. You can supply an input and export code page along with a input binary buffer. In this example I am converting a Unicode binary string to Unicode character based string. However it should work just as well for going from Chinese Simplified (GB2312) or Chinese Traditional (Big5) to Unicode (UTF-8).
call function 'SCP_TRANSLATE_CHARS'
exporting
inbuff = e_data
inbufflg = xdocument_length
incode = codepage
* OUTBUFFLG = 0
outcode = codepage
* CSUBST = 'X'
* SUBSTC_HASH = ' '
* SUBSTC_DOT = ' '
substc_space = 'X'
substc = '00035'
importing
* INUSED =
outbuff = cdocument
* OUTOVERFLOW =
* OUTUSED =
* SUBSTED =
* INPUT_ENDS_IN_CHAR =
* ERRMSG =
exceptions
invalid_codepage = 1
internal_error = 2
cannot_convert = 3
fields_bad_type = 4
others = 5.
