In the first case, changing the codec won't affect much code when ported to Py3k. In the second case, a change to the codec is not necessary. Please also consider the following: * without the Unicode escapes, the only way to put non-ASCII code points into a raw Unicode string is via a source code encoding of say UTF-8 or UTF-16, pretty much defeating the original requirement of writing ASCII code only * non-ASCII code points in text are not uncommon, they occur in most European scripts, all Asian scripts, many scientific texts and in also texts meant for the web (just have a look at the HTML entities, or think of Word exports using quotes) * adding Unicode escapes to the re module will break code already using "...\u..." in the regular expressions for other purposes; writing conversion tools that detect this usage is going to be hard * OTOH, writing conversion tools that simply work on string literals in general is easy Thanks, -- Marc-Andre Lemburg eGenix.com Professional Python Services directly from the Source (#1, May 13 2007) >>> Python/Zope Consulting and Support ... http://www.egenix.com/ >>> mxODBC.Zope.Database.Adapter ... http://zope.egenix.com/ >>> mxODBC, mxDateTime, mxTextTools ... http://python.egenix.com/ ________________________________________________________________________ :::: Try mxODBC.Zope.DA for Windows,Linux,Solaris,MacOSX for free ! :::: eGenix.com Software, Skills and Services GmbH Pastor-Loeh-Str.48 D-40764 Langenfeld, Germany.
