How to change default language in outgoing messages?

[Karol]

Hello there,
I would like to change the default western European language for outgoing messages in pocket outlook into default Central European Windows.
Thing is, now I need to go into MESSAGE OPTIONS in the MENU and change the language into Central European every time I send a message.
Is there a registry tweak which would enable me to have Central European Windows for ALL outgoing messages?
With WM2003 it was enough to change the general language settings into Polish and automatically all outgoing messages would show CE fonts.
With WM5 this seems not to be the case. If I prepare a message in CE fonts, these would not show when the message is received by the adressee. But maybe a registry tweak would do? Anybody tried already?

My friend [CpD]bob promted me.
I changed HKLM\nls\SystemLCID value date from 409 to 419 (hex) and rebooted.
Now I have russian codepage as default language instead of western european language.
This can use Wizard's owners too.

Thank you DiscoStar. Further to your indication I found out that the value for Polish is 415. However if I change it and I reboot, it comes back to the default 409. Any ideas?

OK, it works. I applied the above tweak using 415 value, I switched the device off and waited 10 secs. After the soft-reset the value stays on 415 and the defalult language for outgoing messages is Central European ISO.
Now the Polish fonts can be read by the receiver.
I guess it did not work in the first place because i didn' switch the device off and didn't wait the 10 secs. I read somewhere that this is needed for flushing the cache.
Thanks for the tip.
