If I download my site created with a modular system with httracks, there are
texts of in a not readable form. Senseless characters are present.
For example:
"‹í][wÛF’~÷¯h#»‘4!x'ER¢²²,_ßÖrÆ3±}tš@“„”,+ú'û0óæižÆl¿ªnÜHJ¾$žLæÄ'‘H

What do I have to adjust, that this does not happen anymore. But there are
also pages with readable text.
