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.

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. Used in SMTP, NNTP, … ● Personal opinion: browser support was an inside job of the security industry. ● Why? Because: <script>alert(1)</script> == +Adw-script+AD4-alert(1)+ADw-/script+AD4- ● Fortunately (for the defender) support is dropped by browser vendors. Byte Order Mark ● U+FEFF ● Appears as:  ● W3C says: BOM has priority over declaration – IE 10+11 just dropped this insecure behavior, we should expect that it comes back. – http://www.w3.org/International/tests/html-css/character- encoding/results-basics#precedence – http://www.w3.org/International/questions/qa-byte-order -mark.en#bomhow ● If you control the first character of a HTML document, then you also control its character set.

  • Naming Text Encodings to Demystify Them
    Naming Text Encodings to Demystify Them Document #: P1885R6 Date: 2021-08-14 Programming Language C++ Audience: LEWG Reply-to: Corentin Jabot <[email protected]> Peter Brett <[email protected]> If you can’t name it, you probably don’t know what it is If you don’t know what it is, you don’t know what it isn’t Tony Van Eerd Target C++23 Abstract For historical reasons, all text encodings mentioned in the standard are derived from a locale object, which does not necessarily match the reality of how programs and systems interact. This model works poorly with modern understanding of text, ie the Unicode model separates encoding from locales which are purely rules for formatting and text transformations but do not affect which characters are represented by a sequence of code units. Moreover, the standard does not provide a way to query which encodings are expected or used by the environment, leading to guesswork and unavoidable UB. This paper introduces the notions of literal encoding, environment encoding, and a way to query them. Examples Listing the encoding #include <text_encoding> #include <iostream> void print(const std::text_encoding & c) { std::cout << c.name() << " (iana mib: " << c.mib() << ")\n" << "Aliases:\n"; 1 for(auto && a : c.aliases()) { std::cout << '\t' << a << '\n'; } } int main() { std::cout << "Literal Encoding: "; print(std::text_encoding::literal()); std::cout << "Wide Literal Encoding: "; print(std::text_encoding::wide_literal()); std::cout << "environment Encoding: "; print(std::text_encoding::environment());

  • Layout Inference
    LAYOUT INFERENCE: FILE SCHEMA RECOGNITION VIA CONTENT-BASED ORACLES LAYOUT INFERENCE: FILE SCHEMA RECOGNITION VIA CONTENT-BASED ORACLES A dissertation submitted in partial fulfillment of the requirements for the degree of Doctor of Philosophy By Reid A. Phillips University of Arkansas, 2006 Master of Science in Computer Science August 2009 University of Arkansas ABSTRACT Some organizations routinely (e.g., monthly) process tens of thousands of flat files, files consisting of records containing a fixed number of fields, received from third parties. Currently, the process of characterizing each file’s encoding, formatting elements, structure, and content is a manual process, expensive in that the process costs human time, delays processing the files, and is error prone. This dissertation provides methods for automatically inferring the specified meta data associated with these files. In order to mine, persist, transform, or in some other way process structured data contained within a flat file, the properties associated with a file must first be known. Within this paper, the identification of these properties will be referred to as the layout inference problem, where a layout is a specification of the characteristics associated with a file. Typically a manual task, layout inference can benefit from an automated tool designed to replace or assist human involvement in this process. In defining the result of this process, the layout, the first step is to identify the properties to be inferred. These characteristics are requisite to read and process the contents of a file and include but are not necessarily limited to: the schema of the data records contained within a file, the character encoding, and other formatting details.
