Tests of Unicode file encodings and Japanese/English display

I saved a file containing Japanese and English text with different charsets and file save types. All files have lang=ja set in the html tag. I tested them on (the browser formerly known as) Chimera 0.6, Safari beta v62 and MSIE 5.2 (all for Mac). Here are the results Sorry this is so ugly!

divtest4.html - charset=iso-8859-1, file format=standard
layout and English display ok, Japanese only displays if your browser's default text encoding is Shift-JIS or Japanese MacOS.
divtest5.html - charset=utf-8, fle format=standard
as above, but a different kind of mojibake (garbled text for the Japanese)
divtest6.html - charset=iso-8859-1, file format=Unicode, including a Byte Order Mark and with Mac line break characters
displays fine on Chimera and Safari, but MSIE displays the raw html code. Its interesting that the Japanese displays considering the charset - it looks like the file format is 'stronger'
divtest7.html - charset=utf-8, file format=Unicode, + BOM/Mac line breaks
as above
divtest8.html - charset=utf-8, file format=Unicode, + BOM/Unix line breaks
as above
divtest9.html - charset=utf-8, file format=Unicode, + BOM/DOS line breaks
as above
divtesta.html - charset=utf-8, file format=Unicode, + BOM/Unix line breaks, plus utf-8 encoding
both types of text and the layout now display in MSIE, however there's an additional line at the top of the file containing a Euro symbol (€). Safari also displays a blank line (about 10px extra space over divtest9.html). The body tag is becide the content div - there's no whitespace character there. (from the BBEdit manual "UTF-8 encoding is a more compact variant of Unicode that uses 8-bit tokens where possible to encode frequently-used sequences from the file. (This format makes it easier to view and edit content in non-Unicode-aware editors.)")
