Looks like instead of fixing the function naming/documentation for big endian (which I think would have been the better choice by far) simdutf decided to do a full breaking change and treat char16_t*s as char* instead…

I guess this means that we'll need to add something like

constauto simdutf_convert_utf8_to_utf16 = IsLittleEndian() ? simdutf::convert_utf8_to_utf16le : simdutf::convert_utf8_to_utf16be;

for all simdutf functions we intend to use and then use that instead.

@anonrig Would you be up for adding functions to simdutf that just use host endianness, as one would expect for functions that take a char16_t argument? e.g. simdutf::convert_utf8_to_utf16?

Thanks for the mention @addaleax. I'll add this to simdutf.

On a little-endian system, then the following test should pass...

constchar utf8source[] = "\xe7\x8c\xab"; char16_t u16output; size_t u16len = simdutf::convert_utf8_to_utf16le(utf8source, 3, &u16output); size_t u16len = simdutf::convert_utf8_to_utf16le(utf8source, 3, &u16output); EXPECT_EQ(u16len, 1u); EXPECT_EQ(u16output, 0x732B);

On a big-endian system, you will need to replace the last line with...

EXPECT_EQ(u16output, 0x2B73);

(I understand that it is not what you want.)

The simdutf PR is also a great idea. Go!

[anonrig]

When my pull request is merged, we can release a new version on simdutf, and update node.js (and remove the endianness test)

Please consider release 3.0.0 which contains @anonrig's pull request.

[anonrig]

I'll close this pull request, and wait for the github workflow to pick up the 3.0.0 release. Thanks everyone!
