here's one way to do it. cannot think of something more
efficient right now, but I'm sure Tim or Christian will come
up with something...
import array, string
# character that may be overwritten
BLANKS = " ."
# merge overlapping pieces
pieces = string.split(line, "\r")
if not pieces:
a = array.array("c", pieces)
for s in pieces[1:]:
n = len(a)
if len(s) > n:
a[n:] = s[n:] # tail
# handle overlapping part
n = min(n, len(s))
for i in range(n):
if s[i] not in BLANKS:
a[i] = s[i]
# try it out
text = "Bla Bla Bla..........Bla Bla Bla\r............12345..........\r\n"
for line in string.split(text, "\n"):
