[TYPO3] Converting a new fresh install of TYPO3 to UFT-8

[Stephen Bungert]

Hello Listreaders,

I found this site:

http://www.typo3-media.com/blog/article/utf8-and-typo3-updated.html

 very useful when making a TYPO3 install use UFT-8. Now TYPO3 is
pre-installed, for some reason as latin1_swedish_ci.

The above site talks about converting an existing database, but I'm stuck by
the first line:

1. Open a lhell on your TYPO3 server

What is lhell, and how do I open one?
