tdf#130080 soffice.sh: Avoid exporting empty LC_ALL
The previous way of doing
LO_SAVE_LC_ALL="$LC_ALL"
LC_ALL=C
export LC_ALL
# ... (call some tools,...)
LC_ALL="$LO_SAVE_LC_ALL"
resulted in the LC_ALL environment variable explicity being
set to an empty string in case it was not set at all previously.
For some reason, an LC_ALL explicitly set to an empty string
(other than an unset LC_ALL) makes the system ICU on various
Linux distributions assume an "US-ASCII" encoding, even if the
locale is otherwise configured to be a UTF-8 one.
Since the corresponding detection from ICU is used in the
KF5/Qt stack, that resulted in the Plasma-native file picker
assuming an ASCII-encoding, and thus having problems with
files containing non-ASCII characters.
To avoid this, don't export LC_ALL if unset or set to an
empty string.
A big thanks to frinring on IRC #kde-devel for the analysis
of why the Plasma-native file picker is affected by LC_ALL being
set to an empty string!
I could also reproduce that the following sample program run
with 'LC_ALL=' on KDE Neon Developer edition printed "US-ASCII"
when using the system ICU, while it printed "UTF-8" when using
a self-built ICU as of current master (commit
d6b88d49e3be7096baf3828776c2b482a8ed1780) instead, but did not
further investigate why:
#include <unicode/ucnv.h>
#include <iostream>
int main() {
std::cout << ucnv_getDefaultName();
}
