[Typo3] Convertion of – in the RTE

[Anton Liebetrau]

Hi all,

I want to enter the character "n-dash" in the Rich Text Editor (RTE). For
that, I change to the source code mode in the RTE and enter the html name
– (or the unicode –). After saving the text, the – is
converted to a n-dash-character with the ascii-code 150. That's okay for a
Windows charset, but wrong for the ISO-8859-1 encoding (I use this default
enconding for my web site, and the html validator on www.w3c.org registers
an error --> "non SGML character number 150").

For an ISO-8859-x encoding only the ascii-codes 32-127 and 160-255 are
valid. The codes 0-31 and 128-159 are invalid.

How can I suppress the convertion of the – (or — © etc.) in
the RTE?

Thanks for help, Anton
