3. Byte array ext. 16 binary string
For each byte, first and 0xFF to do with the operation, and then use
UTF-8 format:
Note: X represents a value of 0 or 1. The range field is in hexadecimal notation, And the encoding form field is in binary notation.
Range encoding format
0x000000000000-0x0000007f 0 xxxxxxx
0x00000080-0x000007ff 110 XXXXX, 10 xxxxxx

0x0000000-0x0010ffff 11110xxx, 10 xxxxxx, 10 xxxxxx, 10 xxxxxx
The UTF-16 format is as follows:

That day to write a script, you need to turn the hexadecimal number into a decimal, found do not know how to do, search, the original is very simple, than with C language or something easier, on some ready-made orders to solve.Two simple methods are listed first:1) Echo can achieve it by itself, quite simply. However, you do not know what to write if you want to convert from decimal to hexadecimal.]$ echo $ ((0XAC))1722) printf can also oh, hexadecimal and decimal conversions are fine.]$ printf%

The 16 and 10 transformations encountered in recent industrial control projects are easier to implement in. NET, where no direct conversions are found in SQL Server, especially long numbers that are out of range, that is, unsigned 64-bit integers stored in SQL Server. Many of the methods found on the Web apply only to 32-bit integers and 64-bit positive integers, and 64-bit negative numbers cannot be implemented, and the conversion methods used are re

Yesterday wrote a method, can be embedded C commonly used uint8_t data converted to a character, but the program has a warning, embarrassing attack is very uncomfortable, so in today solve the problem. Yesterday's BlogChar in C is a byte, or 8 bits, that can be represented as a number of 2 16 binary. But the first bit is the sign bit, and the microcontroller uses the C language often does not involve negative numbers, so more common is to use unsigned
