Hi,

no, I don't want to write a keylogger
I noticed that Android is probably last mobile OS that doesn't convert national (unicode encoded) characters to english ones on the fly when used in SMS.
I was thinking about an app that would reside reside between software keyboard (stock SenseUI for example) and messaging application and convert national characters like Ś, Ą and make them english ones S, A so I could get 160 vs 70 max characters in SMS.
The other method could be positioning after the messaging application and convert during sending out, instead of typing in like in the first case.
Could it be possible to code?
No, I don't want to code my own keyboard or messaging application

why do you think that when you one or two polish A with ogonek your message will be truncated to ~70 characters?

answering to myself: i didn't know sms uses stupid utf-16 encoding

Yes it does.
Symbian does conversion on the fly when sending out, Android doesn't.
I also came up with another idea if previous two are impossible.
I could write transparent/passthru "keyboard" that would lunch the real one.
Something like:
1. choose "transparent" keyboard as an input method in SMS app
2. transparent keyboard opens up and launches real one like stock Android/HTC/any other
3. real keyboard types into my application and my application types into SMS app

real keyboard->passthru keyboard converting characters->sms APP

as far i know your first two solutiions cannot be done

have no idea of your last idea, sorry
