    nConversionSetting

    Conversion

    1

    Converts single-byte characters in cExpression to double-byte characters.

    Supported for Locale ID only (specified with the nRegionalIdentifier or nRegionalIDType parameters).

    2

    Converts double-byte characters in cExpression to single-byte characters.

    Supported for Locale ID only (specified with the nRegionalIdentifier or nRegionalIDType parameters).

    3

    Converts double-byte Katakana characters in cExpression to double-byte Hiragana characters.

    Supported for Locale ID only (specified with the nRegionalIdentifier or nRegionalIDType parameters).

    4

    Converts double-byte Hiragana characters in cExpression to double-byte Katakana characters.

    Supported for Locale ID only (specified with the nRegionalIdentifier or nRegionalIDType parameters).

    5

    Converts double-byte characters to UNICODE (wide characters).

    6

    Converts UNICODE (wide characters) to double-byte characters.

    7

    Converts cExpression to locale-specific lowercase.

    8

    Converts cExpression to locale-specific uppercase.

    Supported for Locale ID only (specified with the nRegionalIdentifier or nRegionalIDType parameters).

    9

    Converts double-byte characters in cExpression to UTF-8

    10

    Converts Unicode characters in cExpression to UTF-8

    11

    Converts UTF-8 characters in cExpression to double-byte characters.

    12

    Converts UTF-8 characters in cExpression to UNICODE characters.

    13

    Converts single-byte characters in cExpression to encoded base64 binary.

    14

    Converts base64 encoded data in cExpression to original unencoded data.

    15

    Converts single-byte characters in cExpression to encoded hexBinary.

    16

    Converts single-byte characters in cExpression to decoded hexBinary.

  • nRegionalIdentifier
    Specifies the Locale ID, code page, or FontCharSet value to use for the conversion. If nRegionalIDType is omitted, the Locale ID is used for the conversion. If nRegionalIdentifier is omitted, the system locale ID is used by default.

    If nRegionalIdentifier is invalid or not supported on the machine, the error "Invalid locale ID" is generated.
