Thus, there is noneed to define all accented characters (e.g., \‘a, \’a, \^a, \~a, \"a, \r{a}, \k{a},\u{a}), which will make the configuration files look much nicer and easier tomaintain. If a single character of an inheritance list should have a different value,one can simply override it.The optional argument may be used to restrict the list to some features,and to specify an input encoding.3522 3523 \renewcommand*\DeclareCharacterInheritance[1][]{%3524 \let\MT@extra@context\@empty3525 \let\MT@extra@inputenc\@undefined3526 \let\MT@inh@feat\@empty3527 \setkeys{MT@inh@}{#1}%3528 \MT@begin@catcodes3529 \MT@set@inh@list3530 }Safe category codes.3531 \def\MT@set@inh@list#1#2{%3532 \MT@ifempty\MT@inh@feat{%
