Some of the most common file formats for digital data used in eScience (CSV, XML, and JSON, for example) are built atop plain text standards. Plain text representations of digital data are often preferred because plain text formats are relatively stable, and they facilitate reuse and interoperability. -

Fun with Unicode - an Overview About Unicode Dangers

UTF-8 ● Often used in Internet communication, e.g. the web. ● Efficient: minimum length 1 byte ● Variable length, up to 7 bytes (theoretical). ● Downwards-compatible: First 127 chars use ASCII encoding ● 1 Byte: 0xxxxxxx ● 2 Bytes: 110xxxxx 10xxxxxx ● 3 Bytes: 1110xxxx 10xxxxxx 10xxxxxx ● ...got it? ;-) UTF-16 ● Often used for internal representation: Java, .NET, Windows, … ● Inefficient: minimum length per char is 2 bytes. ● Byte Order? Byte Order Mark! → U+FEFF – BOM at HTML beginning overrides character set definition in IE. ● Y\x00o\x00u\x00 \x00k\x00n\x00o\x00w\x00 \x00t\x00h\x00i\x00s\x00?\x00 UTF-7 ● Unicode chars in not 8 bit-safe environments.

No U+FFFD Generation for Zero-Length Content Between ISO-2022-JP Escape Sequences
No U+FFFD Generation for Zero-Length Content between ISO-2022-JP Escape Sequences Henri Sivonen ([email protected]) 2020-08-06 UTR #36: Unicode Security Considerations says1, in part: Character encoding conversion must also not simply skip an illegal input byte sequence. Instead, it must stop with an error or substitute a replace- ment character (such as U+FFFD ( � ) REPLACEMENT CHARACTER) or an es- cape sequence in the output. (See also Section 3.5 Deletion of Code Points.) It is important to do this not only for byte sequences that encode characters, but also for unrecognized or "empty" state-change sequences. For example: […] • ISO-2022 shift sequences without text characters before the next shift sequence. The formal syntaxes for HZ and most CJK ISO-2022 variants require at least one character in a text segment between shift se - quences. Security software written to the formal specification may not detect malicious text (for example, "delete" with a shift-to-double-byte then an immediate shift-to-ASCII in the middle). Background Previously, Gecko, the engine of Firefox and Thunderbird, used a character encod- ing conversion library called uconv, which did not implement the above advice and, like Internet Explorer, did not generate an U+FFFD when two ISO-2022-JP es- cape sequences occurred without any content between them. In Firefox 56, Gecko switched form uconv to encoding_rs, which is a newly-written character encoding conversion library that generates U+FFFD when no content oc- cur between ISO-2022-JP escape sequences, because the above advice from UTR #36 is embodied in the algorithm2 specified in the WHATWG Encoding Standard. -
Representing Information in English Until 1598
In the twenty-first century, digital computers are everywhere. You al- most certainly have one with you now, although you may call it a “phone.” You are more likely to be reading this book on a digital device than on paper. We do so many things with our digital devices that we may forget the original purpose: computation. When Dr. Howard Figure 1-1 Aiken was in charge of the huge, Howard Aiken, center, and Grace Murray Hopper, mechanical Harvard Mark I calcu- on Aiken’s left, with other members of the Bureau of Ordnance Computation Project, in front of the lator during World War II, he Harvard Mark I computer at Harvard University, wasn’t happy unless the machine 1944. was “making numbers,” that is, U.S. Department of Defense completing the numerical calculations needed for the war effort. We still use computers for purely computational tasks, to make numbers. It may be less ob- vious, but the other things for which we use computers today are, underneath, also computational tasks. To make that phone call, your phone, really a com- puter, converts an electrical signal that’s an analog of your voice to numbers, encodes and compresses them, and passes them onward to a cellular radio which it itself is controlled by numbers. Numbers are fundamental to our digital devices, and so to understand those digital devices, we have to understand the numbers that flow through them. 1.1 Numbers as Abstractions It is easy to suppose that as soon as humans began to accumulate possessions, they wanted to count them and make a record of the count. -

These modes are all actually set via a bitmask. Both of the above tests pass on Cygwin , so the default line terminator is :DOS. Beginning with Perl 5. Its line terminator mode is ignored. To that end you should avoid writing to files by name, and instead explicitly open and close the connection yourself. They have bytes. Thanks James and Paul During recent history, data is moved around a computer in 8-bit chunks, often called "bytes" but also known as "octets" in standards documents. Introduction It causes many mojibake unreadable character problems for all computer users. More reasons may have been given that I do not remember anymore. To find out in detail which encodings are supported by this package, see Encode::Supported. Sequences of zeroes and ones. This is a stateful 7-bit encoding. And here is a Wikipedia article on the Han unification issue: en. Fortunately, we can avoid this altogether by using unicode code points in the string literal explicitly:. Default encodings Perl 5. Do not treat the return value as indicative of success or failure, because that isn't what it means: it is only the previous setting. What if we want to represent non-English characters? It indicates whether a string is internally encoded as "utf8", also without a hyphen. -
