struct skip_bom_result
{

};
Attempts to validate that the encoding type matches the character width, and skips past a bom if present in the range defined by [first, last).
| Parameter | Description |
|---|---|
| first, last | Input iterators that demarcate the range of characters to validate. The character type may be any integral type, signed or unsigned, with size in bits of 8, 16 or 32. |
On success, returns a value of type skip_bom_result with pos pointing to the bom if present, otherwise to first, and a value initialized encoding_errc.
On error, returns a value of type skip_bom_result with pos pointing to the location in the range [first,last] where validation stopped, and a encoding_errc error code.
