New submission from Sylvain Marie <[email protected]>:
The example in the doc shows
```python
>>> import locale
>>> loc = locale.getlocale() # get current locale
# use German locale; name might vary with platform
>>> locale.setlocale(locale.LC_ALL, 'de_DE')
>>> locale.strcoll('f\xe4n', 'foo') # compare a string containing an umlaut
>>> locale.setlocale(locale.LC_ALL, '') # use user's preferred locale
>>> locale.setlocale(locale.LC_ALL, 'C') # use default (C) locale
>>> locale.setlocale(locale.LC_ALL, loc) # restore saved locale
```
However locale.getlocale() does not return the locale for all categories
(locale.LC_ALL is even not allowed) but the locale for the LC_CTYPE category.
Therefore restoring it using `locale.setlocale(locale.LC_ALL, loc)` does not
actually restore the initial settings, and may even fail on some platforms (on
mine it does).
The correct example should have the first line of code replaced with
```
>>> loc = locale.setlocale(locale.LC_ALL) # get current locale
```
Note: this issue was first reported in the `pandas` library at
