Characters like that are usually unprintable because they are not ASCII, i.e., characters less than 128 in the C (POSIX) locale
isprint() and other functions that classify characters base their decisions on the locale.
Code:
The isprint() function shall test whether c is a character of class print in the program's current locale; see the Base Definitions volume of IEEE Std 1003.1-2001
localedef is used to set up what characters in a non-standard locale are printable.
To answer you question, it sounds like your code is running against a character codeset that is not compliant with your locale - and your old program was not working correctly when it said it could print a non-ascii character.
Hi,
I am newbie in unix and just started learning it. I want to know what is the difference between an executable file and a file (say text file). How to create executable file? What is the extension for that? How to differentiate ? How does it get executed?
Thanks (1 Reply)

hello Folks,
once we compile any C code on Linux, we run the code using "./a.out"..
but can we have an executable for every program so that we can run the code directly without compiling the code every time.
just run the executable and get the output!

ldd
ldd(1) General Commands Manual ldd(1)NAME
ldd - List dynamic dependencies of executable files or shared objects
SYNOPSIS
ldd [-rdV] filename
OPTIONS
Prints warnings for any unresolved data symbol references that would occur as a result of filename being executed. (Checks references to
only data objects, not functions.) Prints warnings for any unresolved symbol references that would occur as a result of filename being
executed. (Checks references to both data objects and functions.) Displays the version of the ldd command.
DESCRIPTION
The ldd command lists the dynamic dependencies of an executable file or shared object: If filename is an executable file, ldd lists the
pathnames of all shared objects that would be loaded as a result of executing filename. If filename is a shared object, ldd lists the
pathnames of all shared objects that would be loaded as a result of loading filename. The ldd command expects shared objects to have exe-
cute permission, and if this is not the case, it will issue a warning before attempting to process the file.
NOTES
The ldd command does not list shared objects explicitly attached by using dlopen().
The ldd command prints the record of shared object pathnames to stdout. The optional list of symbol resolution problems are printed to
stderr.
EXIT STATUS
If filename is not an executable file or a shared object, a non-zero exit status is returned.
EXAMPLES
The following command lists the static dependencies of libXm.so: ldd /usr/shlib/libXm.so The following command lists the static dependen-
cies of libXm.so as well as any unresolved symbol in libXm.so or any of its dependents: ldd -r /usr/shlib/libXm.so
