Relates to KEYMAN-WINDOWS-B.
While this doesn't address the root cause of the exception, it should
prevent this unhandled exception, and adds breadcrumbs to help us see
which code path might be triggering the issue.
Fixes#7656.
If Keyman Developer is installed, but not Keyman for Windows, then
tsysinfo.exe is not present. If a crash occurs, this causes a secondary
crash when trying to display the error handler dialog. In this
situation, we now just show a dialog box with a short message rather
than the more friendly dialog available via tsysinfo.exe.
We could consider adding tsysinfo.exe into Keyman Developer for a future
release.
Fixes#7628.
Indy components do not treat URLs as UTF-8. Our legacy EncodeURL
function (sourced from Indy components) was the same. Discovered we
needed to fixup the parsing of URLs as well as the construction of them;
there may be other places we need to fix, although I did do a search for
the relevant types in TIKE source.
Fixes#7227.
We want to use keyman.com for now even for alpha builds, as
keyman-staging.com is going to be used for transition to Docker-based
hosting, and it will be problematic to try and share that process with
alpha builds.
