Detailed Description

UTF-16 conversion utilities.

Provides utility functions to convert strings of various types of encoding to UTF-16.

Note

The supported encoding types are pretty limited and there might be surprising (or straight-up broken) behavior that goes beyond our control. Use libiconv, ICU, etc. if you want to do more than what is available here.

Enumeration Type Documentation

utf16_mb_encoding_e

enum utf16_mb_encoding_e

Supported encoding types.

Enumerator
MB_ENCODING_CP936	Use CP936 (GB18030-based). Supported by both ConvStrToUnicode() and ConvCharToUnicode().
MB_ENCODING_CP950	Use CP950 (BIG5-based). Supported by both ConvStrToUnicode() and ConvCharToUnicode().
MB_ENCODING_CP932	Use CP932 (Shift-JIS-based). Supported by both ConvStrToUnicode() and ConvCharToUnicode().
MB_ENCODING_CP949	Use CP949 (EUC-KR-based). Supported by both ConvStrToUnicode() and ConvCharToUnicode().
MB_ENCODING_CP874	Use CP874 (TIS-620-based). Supported by ConvStrToUnicode() only.
MB_ENCODING_CP1252	Use CP1252 (ISO8859-1-based). Supported by ConvStrToUnicode() only. Warning This may not work as intended, as it is an alias to CP950 on at least BA742.
MB_ENCODING_UTF8	Use UTF-8. Supported by ConvStrToUnicode() only.
MB_ENCODING_UTF16	Use UTF-16. Supported by both ConvStrToUnicode() and ConvCharToUnicode().
MB_ENCODING_DEFAULT	Use default encoding. On BA742 this is hardcoded to be CP936. Supported by both ConvStrToUnicode() and ConvCharToUnicode().

Function Documentation

ConvCharToUnicode()

UTF16 ConvCharToUnicode ( unsigned int  src, unsigned short  src_encoding  )

extern

Convert a multi-byte codepoint to UTF-16.

Note

Not all encoding types listed in utf16_mb_encoding_e are supported by this syscall. Check the documentation of it before proceeding. Passing unsupported encoding type to this syscall will cause undefined behavior.

Syscall Number

0x100bc

Parameters

src	Multi-byte codepoint.
src_encoding	Encoding type of the input codepoint.

Returns

UTF-16 codepoint.

utf16_mb_encoding_e Supported encoding types.

ConvStrToUnicode()

UTF16 * ConvStrToUnicode ( const void *  src, UTF16 *  dst, unsigned short  src_encoding  )

extern

Convert a multi-byte string to UTF-16.

Note

Passing unsupported encoding type to this syscall will cause undefined behavior.

Syscall Number

0x100bd

Parameters

[in]	src	Source multi-byte string.
[out]	dst	Converted UTF-16 string.
	src_encoding	Encoding type of the input codepoint.

Returns

Converted UTF-16 string.
