>>> f = open('foo', 'wt+', encoding='UTF-16')
>>> f.write('spam ham eggs')
13
>>> f.seek(0)
0
>>> f.read()
'spam ham eggs'
>>> f.seek(0)
0
>>> f.read()
'\ufeffspam ham eggs'
Although the BOM character is a ZERO WIDTH NO-BREAK SPACE, and should
therefore not impose many problems, the behavior is inconsistent and
unexpected.
codecs.open in 2.x suffers from this same behavior.

(For your information, io module had the same problem in Python3: it was fixed in #4862) |

> Fixed: 2.7 (r81459), 2.6 (r81460), 3.2 (r81461), 3.1 (r81462). This fix doesn't work on Windows nor Solaris: it uses "wt+" file mode, whereas "t" in invalid on these OS (does "t" mode really exist?). While fixing this bug, I noticed two other bugs (in StreamWriter). All bugs should be fixed by a new commit: 2.7 (r81471+r81472), 2.6 (r81473), 3.2 (r81474), 3.1 (r81475). |
