Any ideas?

[Alec Thomas]

No idea, can you provide me with a CSV sample that causes this?

[anonymous]

I played around some more, and it wasn´t totally broken after all :-)

• The code doesn´t produce valid html tables when there is a variable number of cells in each line, or blank cells.

• If a blank line is produced above the csv data, it results in a blank table.

• Also, it causes an exception if characters such as æøå is used.

[Alec Thomas]

To fix the first problem would require two passes over the CSV object, the first to determine the total number of columns.

Second problem is not really a problem, it's a misuse IMO :). It also must be a feature of the underlying Python csv module.

And the exception is the one above?

[Alec Thomas]

Apparently the csv module ​does not handle Unicode. I will force the input to ASCII and replace any Unicode characters.

I've also removed the sniffer call as it doesn't actually seem to be necessary.

(In [708]) Fix for lack of Unicode support in Python's csv module. Closes #324
