199767f8919635c4928607450d9e0abb932109ceToomas Soome * is given as an ASCII string, we use a poor man's ASCII to
199767f8919635c4928607450d9e0abb932109ceToomas Soome * Unicode-16 translation. The size of the option string as given

199767f8919635c4928607450d9e0abb932109ceToomas Soome * '\0' is less than LoadOptionsSize. Even if all Unicode-16

199767f8919635c4928607450d9e0abb932109ceToomas Soome * null character will cause a one-off.
199767f8919635c4928607450d9e0abb932109ceToomas Soome * If the string is already in Unicode-16, we make a copy so that
199767f8919635c4928607450d9e0abb932109ceToomas Soome * we know we can always modify the string.

199767f8919635c4928607450d9e0abb932109ceToomas Soome * first count the number of words. Then, after allocating the

199767f8919635c4928607450d9e0abb932109ceToomas Soome * The EFI shell will pass the name of the image as the first
