<!-- Describe the issue -->

In bitcoin-qt, the command line help message should get translated. But after #13190, help message in bitcoin-qt does not get translated to local language.

There is a problem we need to solve, get -lang option before we translate strings

This will not be a problem once the translations are updated. After #13190, the context (as in the object that owns the translation) for the translations changed so Qt thinks that the translations are new translations. This will be fixed once the strings are re-translated for the new context which occurs after the translations update.

There already is one. Strings are only translated for -qt which has a -lang option.

No, they are not new strings. See src/qt/bitcoin.cpp you initialize the gArgs in step 1, but Qt read the translation resources in step 4.

you initialize the gArgs in step 1, but Qt read the translation resources in step 4.

Still the translations will not be there because the context has changed. That requires a translation string update to fix.

You should not just move the arguments setup to after the translator is setup because setting up the translator requires reading a command line argument. Something different needs to be done.
