Convert the UTF‐32 source of given length into UTF‐8 in dstVector.

Synopsis

Declared in <bdlde_charconvertutf32.h>

static
int
utf32ToUtf8(
    bsl::vector<char>* dstVector,
    unsigned int const* srcString,
    std::size_t srcStringLength,
    std::size_t* numCodePointsWritten = 0,
    unsigned char errorByte = '?',
    ByteOrder::Enum byteOrder = ByteOrder::e_HOST);

Description

Load into the destination the UTF‐8 conversion of the UTF‐32 source. Return 0 on success and a non‐zero status otherwise. See the first utf32ToUtf8 overload in this group for full contract details.

Return Value

0 on success and a non‐zero status otherwise

numCodePointsWritten

if non‐null, receives the number of UTF‐8 code points written

errorByte

optional substitute for invalid UTF‐32 values; 0 writes nothing

byteOrder
