## Troubleshooting

- Encoding

In case of encoding error follow the steps on this webpage: [https://www.thomas-krenn.com/de/wiki/Perl_warning_Setting_locale_failed_unter_Debian](https://www.thomas-krenn.com/de/wiki/Perl_warning_Setting_locale_failed_unter_Debian).

root = dblp_data_tree.getroot()

# Output files.

dblp_bracket = open('dblp.bracket', mode='w', encoding="utf8")

dblp_bracket = open('dblp.bracket', 'w')

print("--- Processing each child of DBLP's root.")

import sys

import random

import sys

number = int(sys.argv[1])

filename = sys.argv[2]

with open(filename, encoding='utf-8') as f:

with open(filename) as f:

    lines = f.readlines()

linestoprint = random.sample(range(len(lines)), number)

for ln in linestoprint:

    print(lines[ln].encode('utf8'), end='')

    print(lines[ln], end='')
