    <p>Thanks for the replies, it works!</p> <p>And since the source files are in mixed formats, I added a list of source formats to be tried in sequence (<code>sourceFormats</code>), and on <code>UnicodeDecodeError</code> I try the next format:</p> <pre><code>from __future__ import with_statement import os import sys import codecs from chardet.universaldetector import UniversalDetector targetFormat = 'utf-8' outputDir = 'converted' detector = UniversalDetector() def get_encoding_type(current_file): detector.reset() for line in file(current_file): detector.feed(line) if detector.done: break detector.close() return detector.result['encoding'] def convertFileBestGuess(filename): sourceFormats = ['ascii', 'iso-8859-1'] for format in sourceFormats: try: with codecs.open(fileName, 'rU', format) as sourceFile: writeConversion(sourceFile) print('Done.') return except UnicodeDecodeError: pass def convertFileWithDetection(fileName): print("Converting '" + fileName + "'...") format=get_encoding_type(fileName) try: with codecs.open(fileName, 'rU', format) as sourceFile: writeConversion(sourceFile) print('Done.') return except UnicodeDecodeError: pass print("Error: failed to convert '" + fileName + "'.") def writeConversion(file): with codecs.open(outputDir + '/' + fileName, 'w', targetFormat) as targetFile: for line in file: targetFile.write(line) # Off topic: get the file list and call convertFile on each file # ... </code></pre> <p>(EDIT by Rudro Badhon: this incorporates the original try multiple formats until you don't get an exception as well as an alternate approach that uses chardet.universaldetector)</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
