An encoding form maps a code point to a code unit sequence. A code unit is the way you want characters to be organized in memory, 8-bit units, 16-bit units and so on. UTF-8 uses one to four units of eight bits, and UTF-16 uses one or two units of …

This Unicode encoding is a good choice because you can use a single character encoding to handle any character you are likely to need. This greatly simplifies things. This greatly simplifies things. Using Unicode throughout your system also removes the need to track and convert between various character encodings.

2014年3月31日 · The x-user-defined encoding is a single-byte encoding whose lower half is ASCII and whose upper half is mapped into the Unicode Private Use Area (PUA). Like the PUA in general, using this encoding on the public Internet is best avoided because it damages interoperability and long-term use.

The only possibilities are that the text is accompanied by additional data that indicates the encoding used or the program requires (assumes) that the text has a particular encoding. Similarly, if a computer program must send (output) text to another program or a display device, it must either tell the destination the character encoding used or ...

2018年10月11日 · Note there’s two groups of items in the Encoding menu: Encode in UTF-8 will reinterpret the current data as UTF-8. You should see the text in the editor change as you use this item. Convert to UTF-8 will convert the loaded data from the current encoding to UTF-8. Load the file, and then check the current encoding in the status bar.

2010年3月19日 · You have a mismatch in your character encoding; your string is encoded in one encoding (UTF-8) and whatever is interpreting this page is using another (say ASCII). Always specify your encoding in your http headers and make sure this matches your framework's definition of encoding. Sample http header: Content-Type text/html; charset=utf-8

2011年3月27日 · An interesting point that was noted in the discussion of another answer (which I didn't really think the author needed to delete) is that there is a difference between a character set, which (in the other author's words - don't remember his username) defines a mapping between integers and characters (e.g. "Capital A is 65"), and an encoding ...

2014年2月26日 · If you really can't avoid using a non-UTF-8 character encoding you will need to choose from a limited set of encoding names to ensure maximum interoperability and the longest possible term of readability for your content. Although these are normally called charset names, in reality they refer to the encodings, not the character sets. For ...

2009年3月31日 · ASCII: Single byte encoding only using the bottom 7 bits. (Unicode code points 0-127.) No accents etc. ANSI: There's no one fixed ANSI encoding - there are lots of them. Usually when people say "ANSI" they mean "the default locale/codepage for my system" which is obtained via Encoding.Default, and is often Windows-1252 but can be other locales.

2016年5月12日 · The encoding of a CSV file is determined by the platform/program it was created on. If you don't know the context, chardet is a good start, but know that it's more than a decode old and has no support for emoticons etc. Use encoding=utf-8 is more robust nowadays. –
