Please see code below

First: you need to properly address the "Note". In this case:
fpath=open("../testxt.hpnote")
Second: readline isn't a function, but a method of the object "fpath" that you've created with the "open" function. "open" is an alias for various IO classes. Therefore you need to apply "readline" as a "method" of this object. I store it in a list for further processing, right away.
line = list(fpath.readline())
now you have a list of garbage, of which you can extract your text with:
line = "".join(line[0:len(line):2])
result is a string with an arbitrary amount of additional random characters. Unfortunately MicroPython doesn't have the string method "decode"
may still not be what you want, but perhaps usable somehow.
