you cannot use this getline()-expression reliably if encoding is set to
utf8 and your line contains non-ASCII characters, because getline()[i]
only returns *one* byte of a possible multi-byte sequence, e.g. with
this text
123äöüabc
the commands
let line = getline(1)
for i in range(0, strlen(line) - 1)
echo i . ': ' . line[i]
endfor
prints
0: 1
1: 2
2: 3
3: <c3>
4: <a4>
5: <c3>
6: <b6>
7: <c3>
8: <bc>
9: a
10: b
11: c
In contrast, yanking the character under the cursor with
normal yl
works correctly.
Regards,
Jürgen
