Priority: medium
Bug ID: 66276
Assignee: [email protected]
Summary: MathML export: avoid using combining characters for
accents and diacritical marks
Severity: normal
Classification: Unclassified
OS: All
Reporter: [email protected]
Hardware: All
Status: UNCONFIRMED
Version: 4.2.0.0.alpha0+ Master
Component: Formula Editor
Product: LibreOffice
As indicated in the MathML spec:
"In the UCS there are many combining characters that are intended to be used
for the many accents of numerous different natural languages. Some of them may
seem to provide markup needed for mathematical accents. They should not be used
in mathematical markup. Superscript, subscript, underscript, and overscript
constructions as just discussed above should be used for this purpose. Of
course, combining characters may be used in multi-character identifiers as they
are needed, or in text contexts."
LibreOffice should try to use the non-combining versions when possible. Some of
the work is already done in bug 66024. BTW, "U+20D7 COMBINING RIGHT ARROW
ABOVE" looks really ugly in Firefox so I wonder if it should be replaced by
"U+2192 RIGHTWARDS ARROW", at least for MathML export.
