Other Unicode Encodings

In addition to the required encodings, compilers may support other Unicode encoding schemes natively.

Modula-2 development systems hosted on EBCDIC based computer systems without ASCII or UTF-8 support are required to provide a transliteration utility which must be external to the compiler and convert between EBCDIC and 7-bit ASCII or UTF-8 encoded source text. At minimum, the EBCDIC500 encoding shall be supported by any such transliteration utility.

Modula-2 source text is encoded in 7-bit ASCII or UTF-8 encodings and all compilers on all platforms must at minimum recognise 7-bit ASCII and UTF-8 encoded source text regardless of the actual character set used on the platform.

Modula-2 source text is encoded in 7-bit ASCII or UTF-8 encodings and all compilers on all platforms must at minimum recognise 7-bit ASCII and UTF 8? encoded source text regardless of the actual character set used on the platform.

In addition to the default encodings, compilers may support other Unicode encoding schemes natively.

In addition to the default 7-bit ASCII encoding, compilers may support other Unicode encoding schemes natively. If any such support is added, the compiler shall at minimum recognise the UTF-8 encoding.

Unicode Support

In addition to the default 7-bit ASCII encoding, compilers may support other Unicode encoding schemes natively. If any such support is added, the compiler shall at minimum recognise the `UTF-8 encoding.

Modula-2 development systems hosted on EBCDIC based computer systems without ASCII or UTF-8 support are required to provide a transliteration utility which must be external to the compiler and convert between EBCDIC and 7-bit ASCII encoded source text. At minimum, the EBCDIC500 encoding shall be supported by any such transliteration utility.

Implementors of transliteration utilities may choose whichever digraph or trigraph transliterations they see fit provided that the transliterations are reversible. However, it is safest to follow the transliteration recommendations as their digraphs have been reserved.

Required Encodings

EBCDIC Support

Modula-2 development systems hosted on EBCDIC based computer systems without ASCII or UTF-8 support are required to provide a transliteration utility which must be external to the compiler and convert between EBCDIC and 7-bit ASCII encoded source text. At minimum, the EBCDIC500 shall be supported by any such transliteration utility.

6-bit Character Set Support

In the now unlikely event that a Modula-2 development system is to be hosted on a 6-bit character set based platform without ASCII or UTF-8 support, the system is required to provide a transliteration utility which must be external to the compiler and convert between digraph or trigraph encoded 6-bit representation and 7-bit ASCII encoded source text.

Recommended Transliterations

Implementors of transliteration utilities may choose whichever digraph or trigraph transliterations they see fit provided that the transliterations are reversible. However, it is safest to follow the Character Set Transliterators|transliteration recommendations as their digraphs have been reserved.

Required Encodings

EBCDIC Support

Modula-2 development systems hosted on EBCDIC based computer systems without ASCII or UTF-8 support are required to provide a preprocessor utility which must be external to the compiler and convert between EBCDIC500 and 7-bit ASCII encoded source text.

6-bit Character Set Support

In the unlikely event that a Modula-2 development system is to be hosted on a 6-bit character set based platform without ASCII or UTF-8 support, the system is required to provide a preprocessor utility which must be external to the compiler and convert between digraph or trigraph encoded 6-bit representation and 7-bit ASCII encoded source text.
