// // $Id$ // // Miscellaneous files for developers: // Developer files for testing UTF-8 character sets and functions: ================================================================================ Open these files in test/editor and compare the contents. Test scrolling, move the cursor over the "special" characters (> U+007F), watch cursor movement, drawing artefacts, etc.. CAUTION: Do not 'cat' these files unless you know what you're doing. Especially the cp1252* files can contain control characters that may freeze your screen (xterm etc.). Detailed file description: The "native" encoded files contain 8-bit characters with binary values that can be seen at the top and left borders, resp. (add both). They should look like the image file (cp1252.png) on Windows only (if the current codepage is "Western, CP 1252", a superset of ISO-8859-1). They will look different with other codepages or on Linux, Unix, or Mac OS X. Use these files with FLTK 1.1 or an editor with the corresponding codepage or locale. The UTF-8 encoded files should be usable with FLTK 1.3, FLTK 2, or FLTK 3 (future). They contain UTF-8 encoded characters at the table positions, where the corresponding ISO-8859-1, Windows copepage 1252, or Mac OS Roman characters would be. They should look identical as the image file (cp1252.png) or MacRoman_utf-8.png, resp., on all UTF-8 capable systems. The files with names iso-8859-1_* contain only the ISO-8859-1 subset, i.e. the colums with character codes 0x80 - 0x9F (U+0080 - U+009F) are empty. Mac OS Roman is the Apple Mac native character set before it became Unicode by default (OS X). The corresponding files are ordered as they would appear with the native character set / encoding. The *.html files contain a character encoding meta tag, so that they should be viewable with all standard browsers. They can be used for cut'n'paste and drag'n'drop tests from a 'native' application (browser) to FLTK, e.g. test/editor or test/input. Special Notes: 0x22 (U+0022: "quotation mark") is doubled intentionally. This has been done for better results in test/editor, because otherwise the rest of the file would be shown in blue color (as a comment). 0x98 (U+02DC: "small tilde") may not display correctly on Windows systems. I saw the same effect with other Windows editors as well. The following characters may be displayed "shifted left" by one position. Seems to work correctly on Linux (with UTF-8 encoding). Mac OS Roman: 0xF0 (U+F8FF: "Apple logo") may not be printable, depending on installed fonts on other systems. There may currently be drawing artefacts when moving the cursor forwards and/or backwards over some "special" characters.

Compile with: g++ -o doxystar doxystar.cxx Usage: cat file | doxystar DO NOT USE this for current code development! It is intended for testing of future code reformatting ! // // End of $Id$. //
