Text file encoding

You can use this calculators to encode a text with an encoding.

In the previous article, I already touched on the topic of text encodings, described in more detail Unicode and its UTF-8 representation as a sequence of variable length characters.
This calculator can convert text to several outdated encodings. I call them outdated because, in modern applications, it is possible to use Unicode and its most convenient representation, UTF-8.
However, old encodings can also be useful when you need to compactly encode the text, for example, for subsequent compression and transmission, when the receiving party knows for sure in what encoding the text is transmitted. For example, Russian text encoded in Windows-1251 will take up half the space than text in UTF-8.
So the calculator below allows you to download a file in the selected encoding or view a hexadecimal dump of the encoded text.

You can view the created file using the Text file decoder.

The calculator will return an error if an incompatible encoding is selected. In the case of Unicode, this is not possible - it contains characters from all modern languages. But outdated 8-bit encodings contain a limited set of characters. For text in several languages, the required encoding may not be found at all.
Many encodings were invented for different languages and character sets in the years before Unicode, so choosing the right encoding for your text can be a daunting task. The following calculator finds all encodings compatible with the entered text.
