Hi all,

another babel greek versus TU problem I guess:

% \renewcommand*{\greekfontencoding}{TU}
%  \renewcommand*{\bbl at greek@fontencdef}{greek-euenc}
%  \renewcommand*{\LastDeclaredEncoding}{TU}
\MakeUppercase  {\textalpha }

- without the makeatletter part
	LGR encoding and "A" shows up
- with the makeatletter part
	TU encoding and
	! LaTeX Error: Command \textAlpha unavailable in encoding TU.

BTW, this is not only for the textAlpha, but for several others, too.

Is this a bug in th TU encoding?
