If I enter the following as entrydata for post:
The post actually shows up as:
"test test test"
Though this is recommended conversion when handling URLs, I believe a [percentsign]20 should be left as just that.
The above "%" symbols have been replaced with "[percentsign]" in order to make sure they are not improperly converted... for your viewing pleasure, the following line has been typed with the "%" actually in place. You will see that it has been replaced by spaces.
test test test
In this instance, it makes no REAL difference, as the and " " look the same when rendered in HTML....
however... when attempting to make a A tag with an HREF to a URL that contains a space... this causes problems. If a URL contains a space, that space must be encoded as [percentsign]20.... however, LiveJournal seems to be replacing that encoding with the " " character, and therefore, generating an improper HREF attribute on the A tag.
