With qt5-webengine 5.15.9-3 on Arch Linux, there only was a rebuild:
70aa541b4f
but somehow, we now have some kind of garbage data in the .data section:
...
\x00QtWebEngine/5.15.9 Chrome/87.0.4xternalclearkey
\x00ernalclearkey.diy.differentguid
\x00Portable Documen/usr/src/debug/qtwebengine/src/core/net/proxying_restricted_cookie_manager_qt.cpp
\x00
...
the *actual* string table only seems to follow much later:
...
\x00display
\x00\x00dispatchCallbackOnIOThread
\x00/Cache
\x00DownloadInterruptReason
\x00General network failure
\x00The server has gone down
\x00General server failure
\x00Unexpected server response
\x00Download canceled by the user
\x00shutdownOnUIThread
\x00qrc://
\x00RequestQuotaPermission
\x00\x00\x00\x00/usr/src/debug/qtwebengine/src/core/quota_permission_context_qt.cpp
\x00\x00\x00\x00\x00QtWebEngine/5.15.9 Chrome/87.0.4280.144
\x00 - %04d-%02d-%02dT%0"
...
So let's include the NUL bytes in our regex, to make sure we get the full
variant, not the garbage.
