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 or Windows copepage 1252 characters would
|
|
be. They should look identical as the image file (cp1252.png) 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 x'80' - x'9F' (U+0080 - U+009F) are empty.
|
|
|
|
Special Notes:
|
|
|
|
x'22' (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).
|
|
|
|
x'98' (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).
|
|
|
|
There may currently be drawing artefacts when moving the cursor forwards
|
|
and/or backwards over some "special" characters.

Files:
|
|
|
|
The first file is an image of how it should look:
|
|
|
|
cp1252.png full Windows Codepage 1252 (Western)
|
|
|
|
The following two files contain the full Windows Codepage 1252:
|
|
|
|
cp1252.txt native (Windows) encoding, suitable for FLTK 1.1
|
|
cp1252_utf-8.txt UTF-8 encoding, suitable for FLTK 1.3 and greater
|
|
|
|
The following two files contain only the ISO-8859-1 characters:
|
|
|
|
iso-8859-1.txt native (Windows) encoding, suitable for FLTK 1.1
|
|
iso-8859-1_utf-8.txt UTF-8 encoding, suitable for FLTK 1.3 and greater
|
|
|
|
|
|
|
|
Other developer support files:
|
|
================================================================================
|
|
|
|
doxystar.cxx Use this to reformat doxygen comments (test only).
|
|
|
|
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 !
