import codecs with open('cp_7_9_12_v17_0.fwf', 'rb') as f: raw = f.read() text = codecs.decode(raw, 'cp500') # or 'cp1047' for IBM mainframe library(readr) fwf_positions <- fwf_widths(c(7, 9, 12), col_names = c("field1", "field2", "field3"))

head -5 cp_7_9_12_v17_0.fwf If it’s binary or unreadable, it may be EBCDIC-encoded (from mainframe). Assume the file has 3 fields of widths 7, 9, and 12 characters (no delimiter). cp_7_9_12_v17_0.fwf

If the file is in , convert first:

import pandas as pd colspecs = [(0, 7), (7, 16), (16, 28)] # 7, 9, 12 characters names = ['field1', 'field2', 'field3'] Read fixed-width file df = pd.read_fwf('cp_7_9_12_v17_0.fwf', colspecs=colspecs, names=names, encoding='utf-8') import codecs with open('cp_7_9_12_v17_0

print(df.head())

It sounds like you’re working with a fixed-width file ( .fwf ) that follows a specific record layout — likely from a legacy system, mainframe, or EDI feed. The filename cp_7_9_12_v17_0.fwf suggests it may be a control parameter or copybook-style layout, possibly with record lengths or field positions derived from a COBOL copybook.
