I'm doing linguistics, and I need to show short and long vowels. 

[![Example of the VCC notation with brevis and macron](https://i.stack.imgur.com/OwL5l.jpg)](https://i.stack.imgur.com/OwL5l.jpg)

The `tipa` package handles vowels with the brevis or macron sign over them, but if I use a capital V `\={V}` or `\u{V}` I don't get a capital V with the sign over it: I get a script lowercase v instead.

Edit: Someone points out that without the `tipa` package, this works fine. I hadn't tried that, so thanks! But with `tipa`, it still doesn't. See code, compiled with ShareLaTeX:

```
\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{palatino}
\usepackage{tipa}

\begin{document}

Outside of the \texttt{tipa} IPA environment: \={V}C is equivalent to \u{V}CC.

Within the \texttt{tipa} IPA environment: \textipa{\={V}C is equivalent to \u{V}CC.}

\end{document}

```
