-# Be aware that bitcoind and bitcoin-qt differ in terms of localization: Qt
-# opts in to POSIX localization by running setlocale(LC_ALL, "") on startup,
-# whereas no such call is made in bitcoind.
-#
-# Qt runs setlocale(LC_ALL, "") on initialization. This installs the locale
-# specified by the user's LC_ALL (or LC_*) environment variable as the new
-# C locale.
-#
-# In contrast, bitcoind does not opt in to localization -- no call to
-# setlocale(LC_ALL, "") is made and the environment variables LC_* are
-# thus ignored.
-#
-# This results in situations where bitcoind is guaranteed to be running
-# with the classic locale ("C") whereas the locale of bitcoin-qt will vary
-# depending on the user's environment variables.
-#
-# An example: Assuming the environment variable LC_ALL=de_DE then the
-# call std::to_string(1.23) will return "1.230000" in bitcoind but
-# "1,230000" in bitcoin-qt.
-#
-# From the Qt documentation:
-# "On Unix/Linux Qt is configured to use the system locale settings by default.
-#  This can cause a conflict when using POSIX functions, for instance, when
-#  converting between data types such as floats and strings, since the notation
-#  may differ between locales. To get around this problem, call the POSIX function
-#  setlocale(LC_NUMERIC,"C") right after initializing QApplication, QGuiApplication
-#  or QCoreApplication to reset the locale that is used for number formatting to
-#  "C"-locale."
-#
-# See https://doc.qt.io/qt-5/qcoreapplication.html#locale-settings and
-# https://stackoverflow.com/a/34878283 for more details.
