unicode - Python encoding conversion -

-

i wrote python script processes csv files non-ascii characters, encoded in utf-8. encoding of output broken. so, in input:

"d\xc4\x9bjin hornictv\xc3\xad"

i in output:

"d\xe2\x99\xafjin hornictv\xc2\xa9\xc6\xaf"

can suggest encoding error might come from? have seen similar behaviour previously?

edit: i'm using csv standard library unicodewriter class featured in docs. use python version 2.6.6.

edit 2: code reproduce behaviour:

#!/usr/bin/env python #-*- coding:utf-8 -*-  import csv pymarc import marcreader # pymarc package available pypi: http://pypi.python.org/pypi/pymarc/2.71 unicodewriter import unicodewriter # unicodewriter from: http://docs.python.org/library/csv.html  def getrow(tag, record):   if record[tag].is_control_field():     row = [tag, record[tag].value()]   else:     row = [tag] + record[tag].subfields   return row  inputfile = open("input.mrc", "r") outputfile = open("output.csv", "wb") reader = marcreader(inputfile, to_unicode = true) writer = unicodewriter(outputfile, delimiter = ",", quoting = csv.quote_minimal)  record in reader:   if bool(record["001"]):     tags = [field.tag field in record.get_fields()]     tags.sort()     tag in tags:       writer.writerow(getrow(tag, record))  inputfile.close() outputfile.close()

the input data available here (large file).

it seems adding force_utf8 = true argument marcreader constructor solved problem:

reader = marcreader(inputfile, to_unicode = true, force_utf8 = true)

according inspection of source code (via inspect) like:

string.decode("utf-8", "strict")

i trying use snmp4j snmp bulkget. when ever use snmp4j make call returned responseevent error says "general variable binding error" , data returned equal null. to debug: print out, console, exact oid , version number using in snmp4j. use printed out data snmpwalk on command line. valid results. know sending snmp4j correct pdu correct oid, version number, max repititions, etc. i have used snmp4j , code wrote succesffuly monitor other devices years. don't know different time. leaving me stumped. why "general variable binding error?" causes error? ideas debug? can reproduced? if so, first action should using wireshark or microsoft network monitor capture network packets. my guess agent gives generr response, not surprising, http://www.ietf.org/rfc/rfc1157.txt

the following code takes xmlnode data type , populates dataset object xmlnode content. write dataset's content file. public void populatedataset(xmlnode node) { xmlnodereader reader = new xmlnodereader(node); dataset ds = new dataset(); ds.readxml(reader); system.guid guid = system.guid.newguid(); string name = string.format("{0}{1}_{2}.xml", utility.xmloutputpath, utility.xmloutputfilename, guid.tostring()); //need write "node empty" file if xmlnode object empty of null ds.writexml(name, xmlwritemode.ignoreschema); } the problem encountered 1 scenario not write content file. how determine if xmlnode object null or empty? you can check if node parameter null or has innertext or innerxml properties null or empty, when enter method before creating xmlnodereader .
