Replace chars in SMS

[J.O.D.]

I would like to see a feature that some other software keyboards do have. A way to replace certain chars in SMS with another ones during typing. Something like this: There are two variables, one for "forbidden" characters and another for their replacement characters, e.g. forbidden "úů", replace with "uu". The reason I ask for this is, that when I type in Czech language and extensivly use the prediction (otherwise super feature), I have to use the "special" chars like ů, ú and so on, as these are suggested by the dictionary. However, in SMS, possible length of the message is reduced by 50 % when using these characters, so in SMS it would be much more effective to automatically replace the "forbidden" characters on the fly.
