if it cannot directly map a character this is a perfectly good solution
since the semantics and appearance of the character does not change.

+4.9. How can I find out which version of glibc I am using in the moment?
+
+{UD} If you want to find out about the version from the command line simply
+run the libc binary. This is probably not possible on all platforms but
+where it is simply locate the libc DSO and start it as an application. On
+Linux like
+
+ /lib/libc.so.6
+
+This will produce all the information you need.
+
+What always will work is to use the API glibc provides. Compile and run the
+following little program to get the version information:
+
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+#include <stdio.h>
+#include <gnu/libc-version.h>
+int main (void) { puts (gnu_get_libc_version ()); return 0; }
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+This interface can also obviously be used to perform tests at runtime if
+this should be necessary.
