text = "Hello, 世界"
print(text)

This would output the text “Hello, 世界”, where “世界” is the Chinese characters for “world”.

Overall, Unicode is an essential tool for internationalization and localization in software development, enabling software applications to work with text in any language and making it possible to build applications that can be used by people from all over the world.

# Declare a Unicode string containing text in different languages
text = "Hello, 世界! مرحبا العالم! नमस्ते दुनिया!"

# Print the length of the string
print(len(text))

# Normalize the string
normalized_text = unicodedata.normalize('NFKD', text)

# Print the normalized string
print(normalized_text)

This code declares a Unicode string containing text in English, Chinese, Arabic, and Hindi. It then prints the length of the string and normalizes the text using the `unicodedata` module. The resulting normalized string can be used for further processing, such as tokenization or sentiment analysis.

import unicodedata

# Declare a Unicode string
text = "Héllo, Wörld! 世界"

# Normalize the string
normalized_text = unicodedata.normalize('NFC', text)

# Print the Unicode category of each character in the string
for char in normalized_text:
    print(char, unicodedata.category(char))

# Print the decimal value of the character 'é'
print(unicodedata.decimal('é'))

# Print the name of the character '世'
print(unicodedata.name('世'))

This code declares a Unicode string containing text in English, German, and Chinese. It then normalizes the text using the `normalize()` function and prints the Unicode category of each character in the string. The code also demonstrates how to use the `decimal()` and `name()` functions to obtain the decimal value and name of specific Unicode characters.

import chardet

# Read a file with unknown encoding
with open('myfile.txt', 'rb') as f:
    data = f.read()

# Detect the encoding
encoding = chardet.detect(data)['encoding']

# Convert the byte string to a Unicode string
text = data.decode(encoding)

# Process the text
print(text.upper())

# Convert the Unicode string to a byte string in a specific encoding
data_out = text.encode('utf-8')

# Write the byte string to a file
with open('outfile.txt', 'wb') as f:
    f.write(data_out)

This code reads a file in binary mode and uses the `chardet` library to detect the encoding. It then converts the byte string to a Unicode string and processes the text (in this case, converting it to uppercase). Finally, it converts the Unicode string to a byte string in the UTF-8 encoding and writes it to a file.

import locale

# Set the locale to the user's default
locale.setlocale(locale.LC_ALL, '')

# Define a list of Unicode strings
strings = ['café', 'apple', 'orange', 'pâté']

# Sort the strings using the current locale
strings_sorted = sorted(strings, key=locale.strxfrm)

# Print the sorted list
print(strings_sorted)

This code uses the `locale` module to set the locale to the user’s default and then sorts a list of Unicode strings using the `sorted()` function and the `locale.strxfrm()` function as the key function. The resulting list is printed to the console.

And here’s an example of how to compare Unicode strings using the `unicodedata.normalize()` function:

import unicodedata

# Define two Unicode strings with different byte representations
s1 = 'café'
s2 = 'cafe\u0301'

# Normalize the strings to the NFD form for comparison
s1_norm = unicodedata.normalize('NFD', s1)
s2_norm = unicodedata.normalize('NFD', s2)

# Compare the normalized strings
if s1_norm == s2_norm:
    print('The strings are equal')
else:
    print('The strings are not equal')

This code uses the `unicodedata.normalize()` function to normalize two Unicode strings to the NFD form for comparison. The code then compares the normalized strings and prints a message indicating whether they are equal or not.

import re

# Define a Unicode string with accented characters
s = 'café'

# Define a regular expression pattern to match any word character
pattern = re.compile(r'\w+')

# Use the pattern to find all matches in the string
matches = pattern.findall(s)

# Print the matches
print(matches)

This code uses the `re` module to define a regular expression pattern that matches any word character, and then uses the `findall()` method to find all matches in a Unicode string. The resulting matches are printed to the console.

And here’s an example of how to use a Unicode property to match letters in a regular expression:

import re

# Define a Unicode string with mixed characters
s = 'hello 123 こんにちは'

# Define a regular expression pattern to match any letter
pattern = re.compile(r'\p{L}+')

# Use the pattern to find all matches in the string
matches = pattern.findall(s)

# Print the matches
print(matches)

This code uses the `\p{L}` syntax to define a regular expression pattern that matches any Unicode letter, and then uses the `findall()` method to find all matches in a mixed Unicode string. The resulting matches are printed to the console.
