For how to use C to display Chinese Characters 3: display Chinese and English characters in graphic mode

With the previous theories, it is not that difficult for us to use C to display Chinese characters.
Now, one problem is that when a string contains Chinese and English characters, one English character occupies only one byte because one Chinese Character occupies two bytes.

And their internal code is different. If we still use the method described above, we will certainly print a bunch of garbled characters.

In theory 1, all strings are Chinese characters to avoid this problem.

So how can we solve the problem of mixed display in Chinese and English? In fact, it is not difficult to carefully read the first few paragraphs of theory 1 and you will find that "... as a result, our dos predecessors thought of a way to represent Chinese characters in a group of two numbers, namely, the inner code of Chinese characters, which are rarely used in the ASCII table. The remaining 128 characters are reserved for English characters, that is, the English internal code... ". These words imply a method to distinguish Chinese characters from English characters, that is:
Reads a byte of data from a string. When the maximum binary value is 1, the current character and the next character constitute a Chinese character. The next time you read data from the lower byte
Reads a byte of data from a string. If the maximum binary value is 0, the current character is an English character. The next time you read data from the next byte of the byte

If the theory is hard to understand, let the facts explain everything.
