`pTrim` unexpectedly fails when `pSeparator` is the space character about rapidcsv HOT 2 CLOSED

Hi @matwey - I'm not at a computer now so I haven't checked your issue in detail, but I suspect the use case is similar to #93 which was deemed out of scope for rapidcsv. There was some proposed changes in that issue which you could take a look at if you like, until I review your issue properly.

Hi again - so I can confirm the code in #93 should word for your use-case.

You can use the patch consecutive-separators.patch.txt
attached in this issue to apply to rapidcsv:
git apply consecutive-separators.patch.txt
and then use the mIgnoreConsecutive option like this:

#include <iostream>
#include <vector>
#include "rapidcsv.h"

int main()
{
  rapidcsv::LabelParams labelParams(-1, -1);
  rapidcsv::SeparatorParams separatorParams;
  separatorParams.mSeparator = ' ';
  separatorParams.mIgnoreConsecutive = true;
  rapidcsv::Document doc("test.dat", labelParams, separatorParams);

  std::vector<float> col = doc.GetColumn<float>(1);
  for (auto& val : col)
  {
    std::cout << "Value: " << val << std::endl;
  }
}

Having reviewed this use case before it was concluded that this was out of scope for rapidcsv, so there are no current plans to integrate this patch into rapidcsv.

Feel free to re-open this issue if you have any follow-up questions.
