Parameters

byteUniHandle

(IN) Points to the Unicode converter handle.

byteOutput

(OUT) Points to the output buffer to receive the unterminated byte string (optional).

outputBufferLen

(IN) Specifies the maximum size of the output buffer in bytes.

unicodeInput

(IN) Points to the input buffer containing the Unicode string to be converted.

actualLength

(OUT) Points to the returned length (in bytes) of the converted string (optional). Does not include the NULL terminator.

Return Values

Remarks

By default, NWUXUnicodeToUntermByte converts an unmappable Unicode character into a special unterminated 6-byte sequence. For example, 0x2620 is converted to "[2620]".

By default, NWUXUnicodeToUntermByte does not recognize any special Unicode sequences for conversion. For example, the Unicode string "ab[81]cd" will be returned as the byte string "ab[81]cd".

Call NWUXUnicodeToUntermByte to determine the size of the string before it is converted by setting the byteOutput parameter to NULL. The outputBufferLen parameter will be ignored, a converted string will not be returned, and the length of the string if it were converted will be returned in the actualLength parameter.

See exuniub.c for sample code.
