'T8O5IGVzdCBsZSBjYWbDqSBsZSBwbHVzIHByb2NoZT8=') This method cannot be used to convert UTF-16 into UTF-8 or some other non-SQL Server-supported encoding.īelow is an Inline-TVF encapsulating the steps shown above: GOįROM dbo.ConvertBase64EncodedUTF8ToUTF16LE( Please note that this trick only works for converting from various source encodings into UTF-16 Little Endian (as that is how the XML datatype in SQL Server stores strings internally). In a DB with a Hebrew Collation, it gets the following error:Ĭonversion of one or more characters from XML to target collation impossible This is extremely useful for sending, say, via email, like with an attachment or image in the email. It has the advantage that it can convert mostly any type of byte encoding into a human-readable ASCII stream. This will hopefully reduce ambiguity in other documents, leading to better interoperability. ![]() specified by the default Collation of the current Database:ĬONVERT(XML, '' In a DB with a Latin1_General Collation it works: I think you may have a misconception here Base64 is not necessarily used to protect information. The purpose of this specification is to establish common alphabet and encoding considerations. It’s designed to carry data stored in binary format across the channels, and it takes any form of data and transforms it into a long string of plain text. This is to VARCHAR, but "success" will depend on the Code Page Base64 is a binary to a text encoding scheme that represents binary data in an American Standard Code for Information Interchange (ASCII) string format. This is to NVARCHAR, which will always work:ĬONVERT(XML, '' Où est le café le plus proche? The trick to this trick is that you need to add the declaration (typically omitted) and specify the source encoding: DECLARE NVARCHAR(500) = N'T8O5IGVzdCBsZSBjYWbDqSBsZSBwbHVzIHByb2NoZT8=' ĬONVERT(XML, VARCHAR(500) = CONVERT(VARCHAR(500), 0x4FC3B920657374206C6520636166C3A9206C6520706C75732070726F6368653F Transmit non-English characters reliably across the Internet. For every 3 bytes of input, you get 4 bytes of output, so it’s not. The trick is to convert the Base64 decoded bytes, in their text representation (even with incorrectly converted characters) into XML. Among other things, the use of base64 encoding makes it possible to: Transmit image data reliably across the Internet. Base64 encoding involves turning binary data into ASCII text for the purpose of saving it to text files like XML, or transmitting it over protocols like HTTP, or embedding it into web page files, and many other purposes. Hence, ù is the 8-bit version of the two-byte UTF-8 sequence for ù ( 0xC3 and 0xB9).įortunately, it is possible to convert a UTF-8 encoded string into UTF-16, or even into a non-Unicode Code Page (IF the Code Page supports all characters being converted). SQL Server uses UTF-16 Little Endian only for NVARCHAR data, and even for XML. So, decoding the Base64 gives you back the original UTF-8 sequence of bytes. The problem is that you encoded a UTF-8 encoded string into Base64.
