subsequent minor updates, please see the BabelStone Blog.BabelPad is distributed as a single executable (no installer). Simply download the zipped file, and then unzip the file BabelPad.exe to the desired location on your computer. A help file is available, but is currently out of date. Windows 95, 98 and Me are no longer supported, but if you do need a version of BabelPad that runs under Windows 9X/Me, an unsupported build of BabelPad version 1.9.3 is available here. * BabelPad.zip (for Windows 2000, XP, Vista or 7) [3,228 KB]BabelPad is free and fully functional for personal or commercial use, but you are welcome to make a small donation to help support its contiinued development if you want ($5 suggested).BabelPad Limitations * Horizontal scroll is fixed width, and so some extremely long lines may be truncated when not in Line Wrap mode. * When in Line Wrap mode, it is not possible to scroll into view the trailing part of a line that is so long that it does not completely fit onto the screen. * The Unicode Bidirectional algorithm has not yet been implemented, and so complex bidirectional text may not be displayed as expected. However, simple bidirectional text (e.g. a Hebrew phrase embedded in English text) should display correctly. * Line breaking behaviour does not conform to the Line Breaking Properties specified by Unicode.BabelPad Tips * When making global changes to a huge (multi-megabyte) document, first disable Undo/Redo (Options : Edit Options from the menu). This will greatly improve the speed of Replace operations. * If you want to convert a large file with a high proportion of characters above U+007F to UCN (\uABCD) format, NCR (ꯍ or Ӓ) format or HTML entity (&entity;) format, then Save As and select "ASCII plus ..." from the encoding dropdown list (and then reopen the file if necessary). This takes a fraction of the time compared with selecting the entire document and using the appropriate function from the Convert menu. * If you want to convert a large file with a high proportion of UCN (\uABCD) or NCR (ꯍ or Ӓ) entities to Unicode characters, then check the Convert NCRs and/or the Convert UCNs checkbox when opening the file. This takes a fraction of the time compared with selecting the entire document and using the appropriate function from the Convert menu after the file has been opened. * To enter a single Unicode character by hexadecimal codepoint value, press Ctrl-Q and enter the codepoint value followed by Enter or Space. * To enter a sequence of Unicode characters by hexadecimal codepoint values, select the Unicode Input Mode (Input : Unicode from the menu or "U+" from the Input toolbar), and type in the codepoint values separated by spaces. Press Ctrl-D to return to the default input mode. Alternativel, type the hexadecimal codepoint value and hit Alt-X. * To convert a single Unicode character to its hexadecimal codepoint value, put the cursor immediately after the character to convert, and hit Alt-X. * When entering Tibetan, Mongolian, Manchu or Yi text using BabelPad's custom input methods for these scripts or entering Unicode text as scalar values using BabelPad's Unicode input method, you may access the keyboard normally by using the AltGr key (or Ctrl + Alt if your keyboard does not have an AltGr key). For example, when using BabelPad's Tibetan Input Method, pressing the numeral keys will enter Tibetan digits, but holding down the AltGr key at the same time as pressing the numeral keys will allow Arabic digits to be entered instead. * If you are working with GB2312-encoded documents open and save your files as GB18030 (GB18030 is a superset of GB2312 that has a one-to-one mapping to Unicode).Uniscribe IssuesBabelPad uses Microsoft's Unicode Script processor, Uniscribe (filename usp10.dll), to format and render Unicode text. The more recent a version of Uniscribe you have installed on the computer the better support you will have for complex scripts such as Indic and south-east Asian scripts, Tibetan and Mongolian. The version of Uniscribe that BabelPad is using is indicated in the About BabelPad... dialogue box.Uniscribe should come pre-installed on Windows 2000 and Windows XP, and should also have been installed if you are running Internet Explorer Version 5 or above on other Windows operating systems. However Uniscribe may not be available on some PCs running Windows 95, 98, ME or NT 4.0 that do not have Internet Explorer 5 or above. If when you attempt to run BabelPad, a dialog box entitled "Unable to Locate DLL" with the message "The dynamic link library USP10.dll could not be found in the specified path" appears, this means that Uniscribe is not installed on your PC.Uniscribe is constantly being updated to support new scripts and to add new functionality to existing script support, so it is important that you have the latest possible version of Uniscribe installed on your PC. Even if you do not use complex scripts, you will only get advanced features for Latin script such as ligatures with a recent version of Uniscribe (to see this try entering <s ZWJ t> with Code2000). You may run BabelPad with a particular version of Uniscribe by simply placing a copy of the Uniscribe file (usp10.dll) in the same directory that BabelPad.exe is located.Some versions of Uniscribe may have bugs that may produce unexpected rendering behaviour, or even cause BabelPad to crash. Those that I know of are outlined below : * Versions of Uniscribe greater than Version 1.405.2416.1 may only work correctly when running under the Windows XP operating system. The following unexpected display behaviour may be observed in BabelPad's character map utility when running under Windows 95/98/ME, Windows NT4 or Windows 2000 with a version of Uniscribe that is greater than Version 1.405.2416.1 : o Strange characters displayed in the range U+0000 through U+001F of the Basic Latin block o Strange characters displayed in the range U+0080 through U+009F of the Latin-1 Supplement block o Only digits displayed for Indic scripts (including Tibetan and Mongolian) if the selected font does not have OpenType tables defined for the particular script * Version 1.453.3665.0 has a bug that may cause any application that relies on it to crash if an attempt is made to display any character in the Lao script range. * Version 1.460.3707.0 has a bug that may cause any application that relies on it to crash if an attempt is made to display a sequence of 16 or more consecutive Tibetan letters without a break (i.e. a space, tsheg or shad). * Some early versions of Uniscribe may crash when an attempt is made to display Arabic text with the "Arial Unicode MS" font. * Early versions of Uniscribe have a bug that causes it to return to BabelPad the wrong character position and screen point of Unicode characters outside of the Basic Multilingual Plane when in Right-To-Left (RTL) mode. This means that you may be unable to click on or select text composed of characters from Unicode Planes 1-16 when in RTL layout mode. * Version 1.626.7600.16385 that ships with Windows 7 causes any characters in the Supplementary Multilingual Plane (Plane 1) that are nor defined in Unicode 5.1 to be rendered as two square boxes (this affects Unicode 5.2 additions such as Avestan, Egyptian Hieroglyphs, Imperial Aramaic, Inscriptional Pahlavi, Inscriptional Parthian, Kaithi, Old South Arabian, Old Turkic, Enclosed Alphanumeric Supplement, Enclosed Ideographic Supplement and Rumi Numeral Symbols). If you encounter this problem on Windows 7, you can render the affected characters correctly in BabelPad by disabling shaping and joining (Ctrl+0 [zero]); however complex scripts will not render correctly in this mode.
