Poco::format() doesn't support (space) as a flag like printf() does
printf() supports a space ' ' as a flag in the format specifier. It would be great if Poco::format() supported the same.

@austin-beer, is this stil an issue in Poco 1.13?
If so, can you prepare a fix and create a pull request?
Yes, this is still an issue in Poco 1.13. This switch statement still doesn't handle a space character in the format string: https://github.com/pocoproject/poco/blob/poco-1.13.0-release/Foundation/src/Format.cpp#L35
Unfortunately I don't have time right now to develop a fix for this, but I'll put it on my TODO list to work on if I get time.
Poco::format wraps the C++ streams which don't have an equivalent for this flag. That makes this a pretty difficult feature to implement in Poco. Simply adding a space to that switch isn't going to cut it.
Ah, yes, I didn't realize that. It does make implementing this capability more difficult. Perhaps instead then an exception should be thrown if ' ' is encountered as a format flag so that the un-expected behavior (that it's not supported) is clear to anyone who tries to use it.
