It’s about time Python saw some love with regard to TM convenience  
functions :)

One thing I have learned from all the work put into the ruby support  
stuff is the importance of style guides, and that one should use all  
the module/namespace support from the language to keep it clear what  
is what, which stuff uses what, etc.

So before piling stuff into tm_helpers.py, one should consider these  
things.

I will work out some style guides for ruby, though not sure exactly  
when, but that might serve as inspiration. For the curious, in TM 2 we  
will effectively create a new Support folder which has a more clear  
structure and less noise. Old commands will continue to see the old  
Support folder, but new commands will see the new one, so we can do a  
safe migration (technically this can be done by simple setting  
TM_SUPPORT_PATH based on the version found in the bundle item’s  
property list).

If you embed non-ASCII in a python string, you must prefix it with u.  
That said, can you paste a more full example showing the problem?
