Hey guys I have a problem. I need to write some letters with both tilde and bar or tilde and hat at the same time but I cannot find any functions that allow so. Do you know any?

The accents package turns out to be useful:
\documentclass{article}
\usepackage{accents,graphicx}
\newcommand{\backtildeacc}{%
\raisebox{-1.25ex}[.3ex][0pt]{\reflectbox{\char"7E}}%
}
\newcommand{\btilde}[1]{\accentset{\backtildeacc}{#1}}
\begin{document}
$\tilde{A}\btilde{A}$
\fboxsep=0pt
\fbox{$\btilde{A}$}\fbox{$\tilde{A}$}
\end{document}
Here's a possible solution working in all sizes.
\documentclass{article}
\usepackage{amsmath}
\usepackage{etoolbox}
% fix amsmath's \dddot
\patchcmd{\dddot}{#1}{\kern0pt #1}{}{}
\makeatletter
\DeclareRobustCommand{\barredI}{%
\mathord{\vphantom{I}\mathpalette\@barredI\relax}%
}
\newcommand{\@barredI}[2]{%
\ooalign{%
\hidewidth\@barredIbar#1\hidewidth\cr
$\m@th#1I$\cr
}%
}
\newcommand{\@barredIbar}[1]{%
\check@mathfonts
\ifx#1\displaystyle
\fontsize{\f@size}{\z@}%
\def\@barredIbarkern{0.3}%
\else
\ifx#1\textstyle
\fontsize{\f@size}{\z@}

\usefont{OT1}{cmr}{m}{n}%
\kern-\@barredIbarkern em
\raisebox{-.5ex}{\symbol{'26}}%
}
\makeatother
\begin{document}
$\barredI_{\barredI_{\barredI}}$ $I\barredI$
\bigskip
$\dddot{I}_{\!jk}\dddot{\barredI}_{\!jk}$
\end{document}
