I am using Central European (specifically Windows 1250) Document Encoding. This is because I edit most of my pages with a windows based text editor (Kedit for Windows), and then view them with Netscape 4.50. Many of my pages use polish accented letters, but they should automatically select the correct font in your browser. If not, it would help to set your browser to use a Latin-2 font (in Netscape 4.5, select View, Character Set, Central European (Windows-1250) for best results.
I had assumed that the ISO-8859-2 convention for Central European fonts was compatible with the Windows-1250 encoding, but this is not true. A page created under Windows, and then displayed assuming the ISO convention, will have the "a-ogonkiem" letters wrong, both upper and lower case. Look at this page for an example and the character codes: ISO-8859-2.
Alternately a page created with an ISO compliant ediotor, like Netscape Composer 4.5, and then displayed assuming the Windows convention, will have the "a-ogonkiem, s-kreska, and z-kreska" letters wrong, both upper and lower case. Look at this page for an example and the character codes: Windows-1250.
So I've decided to accept window encoding for now, and had make a slight change to the html code on all the pages in February 1999, when I finally realized my mistake.

My main genealogical project is researching the roots of the BARTOLD surname in Poland, and its sources in the name Berthold/Berchtwald in the mists of time.
