Where is that design documented, and how exactly violates the name
the design (chapter and verse, please).
Martin, I designed the whole Python codec machinery, so even if
this is not explicitly written down somewhere, you can take my
word for it.
I don't want users to be confused by such an error handler
name, so please change it !
Here's a list of the currently available error handlers (taken from
codecs.py):
The .encode()/.decode() methods may use different error
handling schemes by providing the errors argument. These
string values are predefined:
'strict' - raise a ValueError error (or a subclass)
'ignore' - ignore the character and continue with the next
'replace' - replace with a suitable replacement character;
Python will use the official U+FFFD REPLACEMENT
CHARACTER for the builtin Unicode codecs on
decoding and '?' on encoding.
'xmlcharrefreplace' - Replace with the appropriate XML
character reference (only for encoding).
'backslashreplace' - Replace with backslashed escape sequences
(only for encoding).
The set of allowed values can be extended via register_error.
Error handlers and codecs are two different things, so the namespaces
need to be clearly separate.
They *are* separate naemspaces; that's guaranteed by the implementation.
In the implementation, yes, but not in the head of a typical user:
the 'utf8b' looks more like a codec name than an error handler
name.
Judging by the existing names, I think that 'surrogate' would be
reasonable. It already contains the meaning of substitute, it's not too
long, and the codes which act as replacements are already called
surrogates.
I want to avoid any such confusion with Python codecs and don't
understand why you are making a problem out of this.
