Problem to get header content! about csv-parser

[dangdkhanh]

Hi,
I realized the problem lies with the unicode characters that are at the beginning or end of each cell. will cause field_start and field_length calculations to be incorrect.
The temporary way I came up with is to use a variable that defines the boundary:

const BOOL checkboundary(char x) {
return x == '\t' || x == ',';
};
const auto& isbeginend = data_pos == 0 || (data_pos > 1 &&
((!checkboundary(this->data_ptr->data[data_pos]) && checkboundary(this->data_ptr->data[data_pos - 1])) ||
(!checkboundary(this->data_ptr->data[data_pos]) && data_pos < size - 1 && checkboundary(this->data_ptr->data[data_pos + 1]))));

From there recalculate the flag:

const auto& flag = compound_parse_flag(in[data_pos], isbeginend);

It may work in some cases but not completely.
