UnicodeDecodeError error from in get_pynagField

[arthur sherman]

i get  "UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 68: ordinal not in range(128)"

when attempting a subsequent edit of an object via adagios.

the initial edit of an object is error free. (this took some adjustment of the locale.)

locale on the nagios server and web clients are the same.

there's lots written on how to code around this error, but i'm not a coder (unless there's no choice).

any suggestions?

i'm using adagios 1.6.1, nagios 4.1.1, debian 8 (jessie)

here's the traceback:
