Unicode Data Browser
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.
Unicode Description Utilities
The Unicode Description Utilities is a set of four programs for finding out what is in a Unicode file.
UnRTF is a command-line converter from RTF (Rich Text) to HTML, LaTeX, PostScript, plain text, and text with VT100 codes. When converting to HTML, it supports tables, fonts, embedded images, hyperlinks, paragraph alignment, and more.
Unsort unsorts a textfile. In other words: it randomizes the order of the lines in a file.
utf2any translates a file encoded in UTF-7 or UTF-8 (Unicode) into any 7- or 8-bit text format.
vcomment is a very small and simple tool that attempts to show every line with a comment (both C++ style double slash, and original C 'slash-star-star-slash' matched quotes) inside one or more files.
An html to ascii or utf-8 converter specifically programmed to output text suitable for reading.
a small Python program which removes much of the HTML cruft produced by Microsoft Word 2002 (Word version 10), making them much easier to hand-edit

xroottext renders stdin onto the root window with line wrap and scrolling.
xtranslate is a tool to convert the text in the X11 selection buffer from ASCII to arbitrary UTF-8 characters. This is particularly useful when you've accidentally typed some text while the keyboard was in the wrong language mode.
