#UTF 8 CONVERTER PYTHON CODE#
Since it is difficult to imagine a character used in popular applications, environments, or operating environments that does not have its own code point in UTF-8, specifying the error handling method can be neglected.Today’s programs need to be able to handle a wide variety ofĬharacters. With encode(), we first get a byte string by applying UTF-8 encoding to the input Unicode string, and then use decode(), which will give us a UTF-8 encoded Unicode string that is already readable and can be displayed or to the console to the user or printed. Method 1 Built-in function encode() and decode() Python Convert Unicode to UTF-8ĭue to the fact that UTF-8 encoding is used by default in Python and is the most popular or even becoming a kind of standard, as well as making the assumption that other developers treat it the same way and do not forget to declare the encoding in the script header, we can say that almost all string handling tasks boil down to encoding/decoding from/to UTF-8.įor this task, both of the above methods are applicable. Note that if preserve is used, the string returned by unidecode() will not be ASCII encoded! Read more here. The preserve will save the original non-ASCII character in the string.
replace will replace them with “?” (or another string specified in the replace_str argument). The exclusion object will contain an index attribute that can be used to find the invalid character.
The default is ignore, which means that Unidecode ignores these characters (replaces them with an empty string). You can also provide an error argument to unidecode(), which determines what to do with characters not present in its transliteration tables. PyPi has a unidecode module, it exports a function that takes a Unicode string and returns a string that can be encoded into ASCII bytes in Python 3.x: >from unidecode import unidecode Namereplace – unsupported characters are replaced with sequences like \NĪs a result, we can get a not quite expected or uninformative answer, which can lead to further errors or waste of time on additional processing. Xmlcharrefreplace – unsupported characters are replaced with their corresponding XML-representation īackslashreplace – unsupported characters are replaced with sequences starting with a backslash Replace – unsupported characters are replaced with “?” Ignore – unsupported characters are skipped Strict – used by default, will raise a UnicodeError when checking for a character that is not supported by this encoding Any encoding can be used in the encoding scheme: ASCII, UTF-8 (used by default), UTF-16, latin-1, etc.
The built-in function encode() is applied to a Unicode string and produces a string of bytes in the output, used in two arguments: the input string encoding scheme and an error handler. Perhaps the most common method to accomplish this task uses the encoding function to perform the conversion and does not use one additional reference to a specific library, this function calls it directly. Unlike the following method, the bytes() function does not apply any encoding by default, but requires it to be explicitly specified and otherwise raises the TypeError: string argument without an encoding. >print(bytes(A, 'utf-8'), type(bytes(A, 'utf-8')))Ī literal b appeared – a sign that it is a string of bytes. Let’s see how it works and immediately check the data type: A = 'Hello' This function internally points to the CPython library, which performs an encoding function to convert the string to the specified encoding. Method 1 Built-in function bytes()Ī string can be converted to bytes using the bytes() generic function. Let’s take a look at how this can be accomplished.
Method 1 Built-in function encode() and decode()Ĭonverting Unicode strings to bytes is quite common these days because it is necessary to convert strings to bytes to process files or machine learning.
