--- Comment #7 from Owen Genat <[email protected]> --- Created attachment 89657 --> https://bugs.freedesktop.org/attachment.cgi?id=89657&action=edit ODT and screenshots showing rendering under v3304 through v4132. This report basically deals with the Unicode FAQ "Q: Yes, I can represent (for example) X with circumflex by use of X with a combining circumflex: <U+0058, U+0302>. But it doesn't display correctly. The circumflex comes out misplaced, not properly over the “X”.": http://www.unicode.org/faq/char_combmark.html#12b There has been steady improvement in LO (and possibly the fonts shown in the attached) with respect to the handling of combining characters. The attached ODT was created under Ubuntu 10.04 x86_64 running v4.1.3.2 Build ID: 70feb7d99726f064edab4605a8ab840c50ec57a and provides an example in 36pt of A (U+0041) combined with these combining marks indicated in the description: - Combining grave accent (U+0300) - Combining acute accent (U+0301) - Combining circumflex accent (U+0302) - Combining tilde (U+0303) - Combining macron (U+0304) ... using the main fonts (not all variants e.g., condensed, mono, etc.) that are distributed with LO v4.1.3.2 as well as Arial and Times New Roman. This document was then viewed under the same OS using these versions of LO (not ideal I know, but still indicative): - v3.3.0.4 OOO330m19 Build: 6 - v3.4.6.2 OOO340m1 Build: 602 - v3.5.7.2 Build ID: 3215f89-f603614-ab984f2-7348103-1225a5b - v3.6.7.2 Build ID: e183d5b - v4.0.6.2 Build ID: 2e2573268451a50806fcd60ae2d9fe01dd0ce24 - v4.1.3.2 Build ID: 70feb7d99726f064edab4605a8ab840c50ec57a Screenshots from each are shown. Obviously the earlier version are not going to render all fonts well as many were not included until a later version (thus there is some font substitution). Even so the results are encouraging. Here is a summary: v3.3.0.4 - Gentium Basic, Gentium Book Basic OK v3.4.6.2 - no change v3.5.7.2 - Linux Libertine G OK, Linux Biolinum G partially OK (tilde and macron display incorrectly) v3.6.7.2 - Liberation Sans, Liberation Serif both have regression in tilde v4.0.6.2 - DejaVu Sans, DejaVu Serif, Arial, Times New Roman OK, Source Code Pro error in general display v4.1.3.2 - Liberation Sans, Liberation Serif, Open Sans, PT Serif, Source Code Pro OK The only outstanding rendering issue as at v4.1.3.2 is with Linux Biolinum G for the tilde and macron characters indicated. Obviously this is not a comprehensive combining character test and so other (untested) fonts and character combinations may render differently. -- You are receiving this mail because: You are the assignee for the bug.
