Sorry, something went wrong.
This change refactors `StringBytes::WriteUCS2()` in multiple ways. The `flags` argument being passed to `WriteUCS2()` is not useful: the only really relevant flag is `NO_NULL_TERMINATION` since V8 ignores `REPLACE_INVALID_UTF8`, `HINT_MANY_WRITES_EXPECTED`, and `PRESERVE_ONE_BYTE_NULL` for UTF-16 strings. However, `WriteUCS2()` might not null-terminate the result correctly regardless of whether `NO_NULL_TERMINATION` is set because it makes multiple calls to `String::Write()` internally. For these reasons, this patch removes the `flags` argument entirely and always assumes `NO_NULL_TERMINATION`. Next, this patch replaces the calls to the deprecated function `String::Write()` with calls to the new function `String::WriteV2()`, which always succeeds and always writes a predictable number of characters, removing the need to deal with a return value here. Lastly, this patch simplifies the implementation of `WriteUCS2()` and computes the exact number of characters `nchars` from the beginning, removing the need to later check again if the number of characters is zero.

Adding dont-land-on-v22.x PRs that should not land on the v22.x-staging branch and should not be released in v22.x. as it looks like WriteV2 is not available on 22.x. |

This change refactors StringBytes::WriteUCS2() in multiple ways.
The flags argument being passed to WriteUCS2() is not useful: the only really relevant flag is NO_NULL_TERMINATION since V8 ignores REPLACE_INVALID_UTF8, HINT_MANY_WRITES_EXPECTED, and PRESERVE_ONE_BYTE_NULL for UTF-16 strings. However, WriteUCS2() might not null-terminate the result correctly regardless of whether NO_NULL_TERMINATION is set because it makes multiple calls to String::Write() internally. For these reasons, this patch removes the flags argument entirely and always assumes NO_NULL_TERMINATION.
Next, this patch replaces the calls to the deprecated function String::Write() with calls to the new function String::WriteV2(), which always succeeds and always writes a predictable number of characters, removing the need to deal with a return value here.
Lastly, this patch simplifies the implementation of WriteUCS2() and computes the exact number of characters nchars from the beginning, removing the need to later check again if the number of characters is zero.
