[Cuis-dev] Can't parse CSV data from file

[Hilaire Fernandes]

Hi,

I investigate a bit the situation, and the problem seems to come from 
identity comparison of character which could be instance of Character or 
instance of UnicodeCodePoint when read from file. So we have identity 
comparison:

peekSeparator
     ^ self peekChar == separator

There is other method in NeoCSV relying on equal identity between 
characters: #peekFor: #peekQuote

Options to fix it:

  * Make the separator a UnicodePoint, most tests should break.
  * Use equality instead of identity => tested, lock the image
  * other...

I added a test to detect that scenario.
