Hi,

Please take a look at the Tizen::Base::Utility::StringUtil class:

i had already seen that my doubt is whether to use 

static ByteBuffer * 

DecodeBase64StringN (const String &base64String)

or

static ByteBuffer *  StringToUtf8N (const String &unicodeString)

Hi,

This depends on type of data containing in your string. The following link provides some examples of possible conversions:

Hi Harish,

static ByteBuffer *  StringToUtf8N (const String &unicodeString) is used to encode Unicode strings to byte sequences.

static ByteBuffer * 

DecodeBase64StringN (const String &base64String)

is used to encode a byte sequence to a string.

So, these are widely different concepts and should not be confused.

Things to keep in mind:

Not every byte sequence represents an Unicode string encoded in UTF-8 or UTF-16.

Not every Unicode string represents a byte sequence encoded in Base64.

Thus if your string contains byte sequences [A-Z] then you should use first option or else second.

 

Thanks.
