i tried the example from http://man7.org/linux/man-pages/man1/getopts.1p.html
and it failed because some invisible chars where embedded

sh -x page.sh
+ aflag=
+ bflag=
+ getopts ab: name
+ '[' '!' $'\342\210\222z' '' ']'
page.sh: line 13: [: −z: unary operator expected
+ '[' '!' $'\342\210\222z' '' ']'
page.sh: line 16: [: −z: unary operator expected
page.sh: line 19: 1 − 1: syntax error: invalid arithmetic operator (error token is "− 1")

this does not happen when i clip the example rendered with groff (aka man).

i guess your problem may have the some origin.
