uni2ascii and ascii2uni provide conversion in both directions between UTF-8 Unicode and more than thirty 7-bit ASCII equivalents, including RFC 2396 URI format and RFC 2045 Quoted Printable format, the representations used in HTML, SGML, XML, OOXML, the Unicode standard, Rich Text Format, POSIX portable charmaps, POSIX locale specifications, and Apache log files. It can also convert between the escapes used for Unicode in languages such as Ada, C, Common Lisp, Java, Pascal, Perl, Postscript, Python, Scheme, and Tcl.
CharEntry is a tool for inserting non-ASCII characters into text, with particular emphasis on linguistic notation. It provides charts of the consonants, vowels, and diacritics of the International Phonetic Alphabet as well as a chart of precomposed accented characters. Clicking on a character inserts it into a text region, the contents of which may be saved to a file or copied and pasted elsewhere. A widget for inserting characters by Unicode codepoint is also provided. Furthermore, it is possible to read the definition of a custom character chart from a file.
UnicodeDataBrowser is a browser for the UnicodeData.txt file, which contains much useful information but is not easily read by humans. It creates a scrollable table in which columns represent properties. The table may be sorted on any column. Abbreviations are expanded and characters cross-referenced in decomposition and casing fields are named. Regular expression search restricted to a selected column is available. The set of characters for which information is displayed may be restricted to those characters matching a regular expression on a specified property.
Trowser is a browser for large line-oriented text files (such as debug traces). It's meant as an alternative to "less". Compared to less, trowser adds color highlighting, a persistent search history, graphical bookmarking, separate search result windows, and flexible skipping of input from pipes to STDIN. Trowser has a graphical interface, but is designed to allow browsing via the keyboard at least to the same extent as less. Key bindings and the cursor positioning concept are derived from vim.
libuninum is a library for converting Unicode strings to integers and integers to Unicode strings. Internal computation is done using arbitrary precision arithmetic, so there is no limit on the size of the integer that can be converted. Values are passed and returned as ASCII decimal strings, GNU MP mpz_t objects, or unsigned long integers. Auto-detection of the number system is provided. Very many number systems are supported. Group delimitation for output strings is fully controllable. Command line and graphical interfaces are also provided.
Boustrophedon Text Reader displays text files in Boustrophedon, a writing style used by the ancient Greeks that alternates direction every line. Once accustomed to the style, a person can gain significant speed in reading and writing. It is of particular interest to those seeking ambidexterity and brain-hemisphere equivalence.
