UnicodeEncodeError when using outside of US #3

For the error see e.g. http://www.markhneedham.com/blog/2015/05/21/python-unicodeencodeerror-ascii-codec-cant-encode-character-uxfc-in-position-11-ordinal-not-in-range128/

Want to see if you can implement the solution the author wrote about there? I wonder if this fix wouldn't do it robustly: ''' import sys reload(sys) sys.setdefaultencoding('utf8') '''

wolframteetz commented 8 years ago

Seems to work fine with that fix ;)

Cool. Wish I had unit tests written to make sure this doesn't break elsewhere, but I'll just assume it doesn't. Bad, bad developer, Drew.

wolframteetz commented 8 years ago

Great developer, answers issues within seconds...

Btw, how did you generate the html code from the python list? Did I miss this?

I have e.g. [[48.1357055, 11.4529908], [48.1237425, 11.4817875], [48.1226858, 11.488059], [48.10884, 11.50052], [48.09478, 11.48443], [48.08183, 11.47625], [48.08584, 11.45199], [48.0878668, 11.4421133], [48.08417, 11.38985], [48.1077838, 11.4094118], [48.12023, 11.41364], [48.13611, 11.42765]]

now, and what I need is

var isochroneCoords5 = [ new google.maps.LatLng(41.8899589,-87.6355558), new google.maps.LatLng(41.886802,-87.6339451), new google.maps.LatLng(41.8869589,-87.632424), (...) ];

Hmmm... this map is going to teach me python in the end I guess? Any chance you have that function with html output flying around? Or is there such a thing in python?

wolframteetz commented 8 years ago

Ok, manually it could work like this for label in isochrone: print 'new google.maps.LatLng('+str(label[0])+","+str(label[1])+"),"

Going to automate this to get a "proper" map like the one on drewfustin.com

drewfustin commented 8 years ago

Yeah, I have a wrapper function inside isocronut.py to call instead of get_isochrone() -- generate_isochrone_map(). Call it the same way with the same inputs as you would get_isochone, but it outputs not only the list of points, but also writes an isochrone.html file. Looking at it now, it might throw an exception if the folder output/ doesn't exist locally.
