Subject: Re: [office] multiple spans

Hi Michael,

I am just working from the ODF Standard and was looking for a property that does not just affect a single character. (In Gnumeric you cannot specify kerning between characters, therefore so far I have not yet to worry about implementation of this.)

If I compare

where styleA includes style:letter-kerning=TRUE and styleB includes style:letter-kerning=FALSE

Then I would think that in the first case there is no letter kerning between D and E but in the second case there is letter kerning between D and E.

how do you implement the second case? you only get letter kerning between 2 characters if you send both of them to the text shaping together, but you can't do that if they have different formatting or a different font, which may well be the case between styleA and styleB.

in LO Writer, the only text-properties attribute that *doesn't* prevent kerning at span breaks is the dreaded officeooo:rsid extension, and that was a pain to implement...
