storing binary infomration in a Unicodestring

what is the best way, if any, to store binary information in a rad studio unicodestring? I intend to transfer this to the database to a Oracle Varchar2 field.
UnicodeString sprint;

   for(int i=0;i<pBlob->cbData ;i++)
	   //pBlob->pbData[i] = bdata[i];

I wear a lot of hats...

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years.

I'd use some encoding. Try to google for base64, for example.
the UnicodeString has a constructor that takes an arbitrary (so also with binary data) buffer:

UnicodeString (UChar *buffer, int32_t buffLength, int32_t buffCapacity)

however i don't see a benefit using the UnicodeString and would suggest for a std::vector instead:

std::vector<unsigned char> buffer;

in the oracle you can't store a blob with binary data to varchar2. beside of the maximum length of 4000 the varchar2 would assume single-byte charset. for unicode string use nvarchar2. for blob data use long or long raw datataype if only one blob field in table. otherwise use blob datatype.
