Hello, I'd like to thank you all for the help. I'd like to ask, what is the `phylosophy' of using <text-settings> and <math-settings> in a \DeclareFontEncoding command? Do these settings remain globally defined after changing the encoding? If so, may be it would be good to provive additional arguments to \DeclareFontEncoding, like <restore-text-settings> and <restore-math-settings>?

I do not like to type unnecessary characters in my texts. :-) -- With best regards, Vladimir.
