Indeterminable locale in export files

[Zimbelstern]

Debian bookworm with gourmand deb package 1.1.0+really1.1.0~rc3-3

When exporting to XML or plain text file, Gourmand uses
a) unlocalised numbers (with dot separator) with translated words
<rating>5.0/5 Sterne</rating>
b) localised numbers with untranslated words
<preptime>0,50 hours</preptime>
c) and sometimes even a dot as a thousands separator
<amount>1.000</amount>
all in the same file.

Localised number formatting causes the floats to be unusable by other programs as the locale is unknown and can not always be determined. I suggest using only dots as decimal separators in exports or to indicate the locale in the file with an attribute (like lang attribute in HTML).
