I'm not sure what your issue is, but the file is supposed to be UCS-2 little-endian like everything else in UEFI. Adding this change would break the parser at the very least as it does not expect a BOM, and then you also need to deal with transcoding back to UCS-2 any additional characters only available in Unicode in the fallback code.

Thanks for your reply, I just found the CSV file format is not as same as CentOS, there is no 'ff fe'
as first two char:
$ make install-deps OSLABEL=AlmaLinux
$ file BOOTAA64.CSV
BOOTAA64.CSV: data
# Hexdump
00000000 73 00 68 00 69 00 6d 00 61 00 61 00 36 00 34 00 |s.h.i.m.a.a.6.4.|
00000010 2e 00 65 00 66 00 69 00 2c 00 41 00 6c 00 6d 00 |..e.f.i.,.A.l.m.|
However, CentOS's BOOTAA64.CSV
:
$ file BOOTAA64.CSV
BOOTAA64.CSV: Little-endian UTF-16 Unicode text
# Hexdump
00000000 ff fe 73 00 68 00 69 00 6d 00 69 00 61 00 33 00 |..s.h.i.m.i.a.3.|
00000010 32 00 2e 00 65 00 66 00 69 00 2c 00 43 00 65 00 |2...e.f.i.,.C.e.|
because first two char 'ff fe'
, if it's doesn't matters, please ignore this PR.
In CentOS and AlmaLinux, the CSV file:
It's unicode file marked by
'ff fe'
characters, however,iconv -t UCS-2LE
