If it succeeds, that encoding is a potential candidate. If that is not enough, I can offer you the Python script I wrote for this answer here, which scans complete files and tries to decode them using a specified character set. Just text and numb3rs and simple punctuation. For example, the byte sequence 303275 (c3 bd in hexadecimal) could be ý in UTF-8, or ý in latin1, or in latin2, or in BIG-5, and so on. Is it possible to detect text file encoding of two possible For example I allow user to use Unicode UTF-8 and iso-8859-2 for their csv files. On the other hand, it also recognizes other common file types like various scripts, HTML/XML documents and many binary data formats (which is all uninteresting for comparing text files though) and it might print additional information whether there are extremely long lines or what type of newline sequence (e.g. It isnt always possible to find out for sure what the encoding of a text file is. It does not know many codecs though and it only examines the first few kB of a file, assuming that the rest will not contain any new characters. However, let's get back from explaining what you can't do to what you actually can do:įor a basic check on ASCII / non-ASCII (normally UTF-8) text files, you can use the file command. That means for example a text saved as UTF-8 that only contains simple latin characters, it would be identical to the same file saved as ASCII. the ASCII encoding is a part of most commonly used codecs like some of the ANSI family or UTF-8.
You must also know that some character sets are actually subsets of others, like e.g. The computer can't really detect which way to interpret the byte results in correctly human readable text (unless maybe if you add a dictionary for all kinds of languages and let it perform spell checks.). The misleading term charset is often used to refer to what are in reality character encodings. Without the key, the data looks like garbage. It is a set of mappings between the bytes in the computer and the characters in the character set. For example, an ä in one encoding might correspond to é in another or ø in a third. A character encoding provides a key to unlock (ie. The problem is that many codecs are similar and have the same "valid byte patterns", just interpreting them as different characters. If you find any bytes that are not valid for a given encoding, it must be something else. What you can easily do though is to verify whether the complete file can be successfully decoded somehow (but not necessarily correctly) using a specific codec. This can be beneficial to other community members reading this thread.You can not really automatically find out whether a file was written with encoding X originally.

All you have to do is give an encoded input and the systems lists different decoded outputs. This tools is useful for people not familiar with encodings and character sets (charsets). This can be beneficial to other community members reading this thread. Help for: Encoding Explorer This is a tool that helps you find the encoding and charset of a text. Please refer this link: Reading from a file. Using (var reader = new DataReader(stream))Īwait reader.LoadAsync((uint)stream.Size) īesides, if you could also accept reading text directly from the storageFile, there are some other ways to read text from a text file.
