BiDi support
|
||||
------------
|
||||
|
||||
Some languages are written right-to-left. In order to display such languages
|
||||
correctly, you need to build VDR with BIDI=1. This will link to the "fribidi"
|
||||
library and implement a function that prepares bidirectional texts to be
|
||||
displayed correctly. Since BiDi support adds some runtime overhead by requiring
|
||||
additional memory allocation and copying, this feature is not compiled in
|
||||
by default, so that users that have no need for this don't get any overhead.
