Here's another one I just found using Google:. It also supports changing it. I needed some basic encoding detection, based on 4 first bytes and probably xml charset detection - so I've took some sample source code from internet and added slightly modified version of. I've done something similar in Python. Basically, you need lots of sample data from various encodings, which are broken down by a sliding two-byte window and stored in a dictionary hash , keyed on byte-pairs providing values of lists of encodings.
If you've also sampled UTF encoded texts that do not start with any BOM, the second step will cover those that slipped from the first step. So far, it works for me the sample data and subsequent input data are subtitles in various languages with diminishing error rates.
The tool "uchardet" does this well using character frequency distribution models for each charset. Larger files and more "typical" files have more confidence obviously.
If you can link to a C library, you can use libenca. From the man page:. Enca reads given text files, or standard input when none are given, and uses knowledge about their language must be supported by you and a mixture of parsing, statistical analysis, guessing and black magic to determine their encodings.
Got the same problem but didn't found a good solution yet for detecting it automatically. Now im using PsPad www. Since it basically comes down to heuristics, it may help to use the encoding of previously received files from the same source as a first hint. Most people or applications do stuff in pretty much the same order every time, often on the same machine, so its quite likely that when Bob creates a.
I was actually looking for a generic, not programming way of detecting the file encoding, but I didn't find that yet. What I did find by testing with different encodings was that my text was UTF UTF7 ;. Thanks Erik Aronesty for mentioning uchardet. Meanwhile the same? Or, on cygwin you may want to use: chardetect. This will heuristically detect guess the character encoding for each given file and will report the name and confidence level for each file's detected character encoding.
Most libraries already mentioned are based on Mozilla's UDE - and it seems reasonable that browsers have already tackled similar problems.
I don't know what is chrome's solution, but since IE 5. It is a native COM call, but here's some very nice work by Carsten Zeumer, that handles the interop mess for. There are some others around, but by and large this library doesn't get the attention it deserves. I use this code to detect Unicode and windows default ansi codepage when reading a file. Copy Code.

I feel sorry, but could correct me if I wrong. Having said "since you can never know what a random bunch of bytes was intended to mean. But how about 1 byte char encodings?
