+Subject: [PATCH] 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();
+    }
