You've got a stray byte floating around. You can find it by running

<pre><code>with open("x.py") as fp:
 for i, line in enumerate(fp):
 if "\xe2" in line:
 print i, repr(line)
</code></pre>

where you should replace <code>"x.py"</code> by the name of your program. You'll see the line number and the offending line(s). For example, after inserting that byte arbitrarily, I got:

<pre><code>4 "\xe2 lb = conn.create_load_balancer('my_lb', ['us-east-1a', 'us-east-1b'],[(80, 8080, 'http'), (443, 8443, 'tcp')])\n"

blocks|key|157980|text|\xe2是'-‘字符，它出现在一些复制和粘贴中，它使用了不同的等同外观的'-’，这会导致编码错误。将'-‘(来自复制粘贴)替换为正确的’-‘(来自键盘按钮)。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|157981|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

\xe2 is the '-' character, it appears in some copy and paste it uses a different equal looking '-' that causes encoding errors.
Replace the '-'(from copy paste) with the correct '-' (from you keyboard button).

blocks|key|4664381|text|对我来说，这个问题是由于引号中的“‘”符号造成的。因为我从pdf文件中复制了代码，所以导致了这个错误。我刚把"'“换成了”‘“。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4664382|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

For me the problem had caused due to "’" that symbol in the quotes. As i had copied the code from a pdf file it caused that error. I just replaced "’" by this "'".

If you want to spot what character caused this just assign the problematic variable to a string and print it in a iPython console.

In my case

<pre><code>In [1]: array = [[24.9, 50.5]​, [11.2, 51.0]] # Raises an error

In [2]: string = "[[24.9, 50.5]​, [11.2, 51.0]]" # Manually paste the above array here

blocks|key|4664487|text|对我来说，问题是在Mac+Notes中输入代码，然后从Mac+Notes复制代码并粘贴到我的vim会话中来创建我的文件。这使得我的单引号成为曲线类型。为了解决这个问题，我在vim中打开了我的文件，并将我所有的弧形单引号替换为直引号，只需删除并重新键入相同的字符。正是Mac+Notes让相同的击键产生了弯曲的单引号。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4664488|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

for me, the problem was caused by typing my code into Mac Notes and then copied it from Mac Notes and pasted into my vim session to create my file. This made my single quotes the curved type. to fix it I opened my file in vim and replaced all my curved single quotes with the straight kind, just by removing and retyping the same character. It was Mac Notes that made the same key stroke produce the curved single quote.

I was unable to find what's the issue for long but later I realised that I had copied a line "UTC-12:00" from web and the hyphen/dash in this was causing the problem. I just wrote this "-" again and the problem got resolved.

I am writing some python code and I am receiving the error message as in the title, from searching this has to do with the character set. 

Here is the line that causes the error

<pre><code>hc = HealthCheck("instance_health", interval=15, target808="HTTP:8080/index.html")

I cannot figure out what character is not in the ANSI ASCII set? Furthermore searching "\xe2" does not give anymore information as to what character that appears as. Which character in that line is causing the issue? 

I have also seen a few fixes for this issue but I am not sure which to use. Could someone clarify what the issue is (python doesn't interpret unicode unless told to do so?), and how I would clear it up properly?

EDIT:
Here are all the lines near the one that errors
