Bug-Description:
|
||
|
|
|
||
|
|
I've just upgraded to readline 5.0 and bash 3.0 and tried them with UTF-8
|
||
|
|
encoding. I found line editing to be quite buggy:
|
||
|
|
|
||
|
|
I type an accented letter, let's say <E1>. Then <E1> appears. I press the left
|
||
|
|
arrow, the cursor goes back, it is now over <E1>. I press <E9>. Now <E9><E1> is
|
||
|
|
visible, which is correct, but the cursor is past the two letters, though
|
||
|
|
it should be over <E1>. Here only the first Left arrow takes affect, moves
|
||
|
|
the cursor over <E1>, but the 2nd time I press Left, it just beeps, doesn't
|
||
|
|
move to the first char (<E9>). Now a Right arrow doesn't move the cursor, but
|
||
|
|
causes further Left and Right arrows to work as expected. To go on,
|
||
|
|
similar bug occurs nearly every time that I insert an accented letter
|
||
|
|
before or amongs other ones (but not at the end of the line). When the
|
||
|
|
command line has about ten or twenty accented letters (and no or hardly
|
||
|
|
any non-accented ones), line editing becomes a total chaos, where
|
||
|
|
sometimes inserting another accented letter causes the cursor to jump many
|
||
|
|
characters to the right, and pressing the Left arrow sometimes causes the
|
||
|
|
cursor to jump back lots of characters at once.
