What is the difference between UTF-8 and UTF-16?

UTF-8 encodes a character into a binary string of one, two, three, or four bytes. UTF-16 encodes a Unicode character into a string of either two or four bytes. This distinction is evident from their names. In UTF-8, the smallest binary representation of a character is one byte, or eight bits.

How do I encode strings to UTF-8?

How do I convert a text file to string?

Python – Read File as String

  1. Open file in read mode. Call inbuilt open() function with file path as argument. open() function returns a file object.
  2. Call read() method on the file object. read() method returns whole content of the file as a string.
  3. Close the file by calling close() method on the file object.

Is a char always 1 byte?

“char” has always been a misspelling of “byte” in C. sizeof(char) has to be 1, but char doesn’t have to be 1 byte in size. It’s more correct to say that sizeof(foo) returns a result relative to sizeof(char).

What is the size of 1 character?

Data Types and Sizes

Type Name 32–bit Size 64–bit Size
char 1 byte 1 byte
short 2 bytes 2 bytes
int 4 bytes 4 bytes
long 4 bytes 8 bytes

Is a character 1 byte?

A byte is the smallest unit of data on a system. In general, 1 byte = 1 ASCII character. 2 bytes = 1 UTF-16 character. An unsigned byte can old the values 0-255.

How many bytes are in a char?

Is UTF-16 same as ASCII?

UTF-16 and UTF-32 are incompatible with ASCII files, and thus require Unicode-aware programs to display, print and manipulate them, even if the file is known to contain only characters in the ASCII subset.

Is UTF-8 and ASCII same?

For characters represented by the 7-bit ASCII character codes, the UTF-8 representation is exactly equivalent to ASCII, allowing transparent round trip migration. Other Unicode characters are represented in UTF-8 by sequences of up to 6 bytes, though most Western European characters require only 2 bytes3.

What is getBytes UTF-8?

How do I read a file into a string?

How do you assign a content to variable in Python?

Here are the steps to read file into string in python.

Using read() method

  1. Open the file in read mode using open() method and store it in variable named file.
  2. Call read() function on file variable and store it into string variable countriesStr .
  3. print countriesStr variable.
