[ 
Right now, this test is focused on 'inline unicode'. Where an author can free-form use language outside the latin character sets. Chinese, Arabic, etc.  The conclusion is that in routine text output, 'say' statements, this seems to work on many interpreters. However, object names, room names, etc - likley will not.

To decide whether unicodage is enabled:
 	(-  glk_gestalt(gestalt_Unicode, 0) -)

Place is a room. "Welcome to the Place. To the west there is a testing room."

The Wild West is west of the Place. "This is Unicode content. A नमस्ते A, B أهلاً وسهلاً B, C 你好 C, D 봉주르 D, E どうもありがとうミスターロボット E. West is another room that is even more wild.".

The Wilder West is west of the Wild West.  "[italic type]This is Italic type. This is Unicode content. A नमस्ते A, B أهلاً وسهلاً B, C 你好 C, D 봉주르 D, E どうもありがとうミスターロボット E. [bold type]This is bold type. This is Unicode content. A नमस्ते A, B أهلاً وسهلاً B, C 你好 C, D 봉주르 D, E どうもありがとうミスターロボット E. [fixed letter spacing]This is fixed letter spacing type. This is Unicode content. A नमस्ते A, B أهلاً وسهلاً B, C 你好 C, D 봉주르 D, E どうもありがとうミスターロボット E.  [paragraph break]UTF-8 Unicode with more than two bytes? 'For example the code point U+9A69 (驩) is encoded as E9 A9 A9'. The gothic letter hwair U+10348 is supposed to be 4 bytes, with a decimal value of 66,376? I pasted one those hwair characters here in the IDE and the Inform 7 6M62 compiler errored with 'Inform can only handle Unicode characters in the 16-bit range, from 0 to 65535.' Another west?"

The West囍ern End is west of Wilder West.  "Je ne suis pour toi qu'un renard semblable à cent mille renards. Mais, si tu m'apprivoises, nous aurons besoin l'un de l'autre. Tu seras pour moi unique au monde. ... Mais si tu m'apprivoises, ma vie sera comme ensoleillée.[paragraph break]Conditional test, do you see Unicode frowns and a happy Arabic greeting? [if unicodage is enabled][unicode 9785][unicode 9785][unicode 9785]. [unicode 9785][unicode 9785][unicode 9785] - enough of that, positive: أهلاً وسهلاً --- IMPORTANT NOTE: The room name should be 'West囍ern End' with Han 'double happiness' U+56cd symbol between 'West' and 'ern'. [otherwise]No, your Interpreter told me no Unicode. Logic test of Unicode said NOT HERE.[end if] More appears to be to the west.".

The A西部B is west of the West囍ern End.  "This is The Westest, named 'A西部B', there are no spaces between the 'A' and 'B', only two Chinese Unicode characters. Even more appears to be to the west.".

The CD is west of the AB. "This is the CD room, west of the AB. Testing on Git interpreter finds you don't end up here going west of the previous room.".

The EF is west of the A B. "This is the EF room, west of the 'A B', space between 'A' and 'B'. If you ended up here, you skipped room CD and the conclusion on Inform 7 build 6M62 is that roon names strip Unicode and compress the high-value characters into a single space.

[Low-level observation #1: The generated Glulx code for the room names seems to always use put_char without unicode for room names.]
