Description Stevan White 2014-12-11 23:52:27 UTC

Characters from high unicode ranges, U+10000 and higher, are rendered very strangely... sometimes using characters from completly different ranges.
For example,  Gothic range (U+10330 - 4a ) is displayed as if it were coming from  Combining Diacritics: (U+0300 - 6F).  Looks like it smply truncates the higher bytes.

Other browsers on Linux render the text of the same page properly.

Reproducible: Always

Steps to Reproduce:
1. Make HTML page with (say) Gothic text, Unicode-encoded
2. Arrange for CSS of the page to load a Unicode font supporting Gothic range
3. Put these on a server, and view with Konqueror

Actual Results:  
What should be Gothic letters are replaced by Combining Diacritics -- but from that font, if it has them.  (This depends on the range of course... Runic letters would result in some other wrong range)

Expected Results:  
To see nice Gothic text

HTML with gothic text

You'll have to supply your own Unicode-encoded Gothic font and appropriate CSS, and then make them available from your server.

CSS will look something like:
@font-face {
        font-family: mygothfont;
        src: url("mygothfont.woff") format("woff"),
        font-weight: normal;
        font-style:  normal;
}

Same page in Firefox

 (By the way, the mess in the Konqueror page are diacritics from the same font... they just lay all on top of one another because they're zero-width.)
