Check if using safe encoding fixes it, see #3

I have checked safe encoding changes are there but still its crashing in container

do you fix it? now ?

[mikegleasonjr]

if you set the global variable SafeEncoding to true on startup, it should not segfault in containers.
@rajendraventurit confirmed it in the PR above.
