Before I discuss this with upstream I'd like to share another observation:
There is some 2to3 magic applied to the source code which has the effect
that the original source code file which has

$ grep -A4 "^TO_SUPERSCRIPT = {" uncertainties/core.py
TO_SUPERSCRIPT = {
    0x2b: u'⁺',
    0x2d: u'⁻',
    0x30: u'⁰',
    0x31: u'¹',

is turned into

grep -A4 "^TO_SUPERSCRIPT = {" uncertainties/core.py
TO_SUPERSCRIPT = {
    0x2b: '⁺',
    0x2d: '⁻',
    0x30: '⁰',
    0x31: '¹',

inside the pbuilder environment.  I hacked around with the following code:

+
+override_dh_auto_test:
+ifeq (,$(filter nocheck,$(DEB_BUILD_OPTIONS)))
+       # for some very strange reason the RefactoringTool breaks the definions in TO_SUPERSCRIPT
+       find . -name core.py -exec sed -i "s/^\([[:space:]]\+0x[0-9a-f]\{2\}: \)'/\1u'/" \{\} \;
+       dh_auto_test
+endif
 

which left me with other test suite failures.  Since I'm totally new to
this package and I have no idea whether this is some Debian specific
build (I had some quite unfriendly conversation with lmfit-py
upstream[1]) so would like to make sure there is no Debian specific
issue first.  (Disclaimer:  I'm totally new to this package as well as
lmfit-py - a Debian Med package just depends from the latter and nobody
else seem to have free time cycles to care.  So please excuse my
naivity.)

Kind regards

       Andreas.
