Mind the *if*.
You'll always create mess when mixing drivers/apps. Ignoring proper
encodings is always non-standard, so don't expect drivers to support it,
and ask for support.
Server encoding is for fixing this issue, and all drivers are obeying
this. So if you want a guarantee to have a working configuration, DO NOT
USE ASCII FOR NON-ASCII DATA.
