- Convert binary buffer to a Unicode String in a specified sequence. \r
-\r
- This function converts bytes in the memory block pointed by Buffer to a Unicode String Str. \r
- Each byte will be represented by two Unicode characters. For example, byte 0xA1 will \r
- be converted into two Unicode character L'A' and L'1'. In the output String, the Unicode Character \r
- for the Most Significant Nibble will be put before the Unicode Character for the Least Significant\r
- Nibble. The output string for the buffer containing a single byte 0xA1 will be L"A1". \r
- For a buffer with multiple bytes, the Unicode character produced by the first byte will be put into the \r
- the last character in the output string. The one next to first byte will be put into the\r
- character before the last character. This rules applies to the rest of the bytes. The Unicode\r
- character by the last byte will be put into the first character in the output string. For example,\r
- the input buffer for a 64-bits unsigned integer 0x12345678abcdef1234 will be converted to\r
- a Unicode string equal to L"12345678abcdef1234".\r

- than 2*N + 1.\r
- @param Buffer The pointer to a input buffer.\r
- @param BufferSizeInBytes Length in bytes of the input buffer.\r

-\r
- @retval EFI_SUCCESS The convertion is successful. All bytes in Buffer has been convert to the corresponding\r
- Unicode character and placed into the right place in String.\r

-/**\r
- Convert a Unicode string consisting of hexadecimal characters to a output byte buffer.\r
-\r
- This function converts a Unicode string consisting of characters in the range of Hexadecimal\r
- character (L'0' to L'9', L'A' to L'F' and L'a' to L'f') to a output byte buffer. The function will stop\r
- at the first non-hexadecimal character or the NULL character. The convertion process can be\r
- simply viewed as the reverse operations defined by BufToHexString. Two Unicode characters will be \r
- converted into one byte. The first Unicode character represents the Most Significant Nibble and the\r
- second Unicode character represents the Least Significant Nibble in the output byte. \r
- The first pair of Unicode characters represents the last byte in the output buffer. The second pair of Unicode \r
- characters represent the the byte preceding the last byte. This rule applies to the rest pairs of bytes. \r
- The last pair represent the first byte in the output buffer. \r
-\r
- For example, a Unciode String L"12345678" will be converted into a buffer wil the following bytes \r
- (first byte is the byte in the lowest memory address): "0x78, 0x56, 0x34, 0x12".\r
-\r
- If String has N valid hexadecimal characters for conversion, the caller must make sure Buffer is at least \r
- N/2 (if N is even) or (N+1)/2 (if N if odd) bytes. \r
-\r
- If either Buffer, BufferSizeInBytes or String is NULL, then ASSERT ().\r
-\r
- @param Buffer The output buffer allocated by the caller.\r
- @param BufferSizeInBytes On input, the size in bytes of Buffer. On output, it is updated to \r
- contain the size of the Buffer which is actually used for the converstion.\r
- For Unicode string with 2*N hexadecimal characters (not including the \r
- tailing NULL character), N bytes of Buffer will be used for the output.\r
- @param String The input hexadecimal string.\r
- @param ConvertedStrLen The number of hexadecimal characters used to produce content in output\r
- buffer Buffer.\r
-\r
- @retval RETURN_BUFFER_TOO_SMALL The input BufferSizeInBytes is too small to hold the output. BufferSizeInBytes\r
- will be updated to the size required for the converstion.\r
- @retval RETURN_SUCCESS The convertion is successful or the first Unicode character from String\r
- is hexadecimal. If ConvertedStrLen is not NULL, it is updated\r
- to the number of hexadecimal character used for the converstion.\r
