I've made significant revisions to the alpha kits and will update the opening post accordingly:
Album:
https://imgur.com/a/twLqZuVAs mentioned previously, I'm working off of the implementations of these keyboards provided by Microsoft Windows 10. Where noted, I'm using Magic Utilities as my primary documentation for Apple layouts. I am not using Linux-specific layouts at this time.
Also, not all AltGr or Shift-AltGr characters may be displayed for a given keyboard and are sometimes omitted for cost/compatibility reasons.
Wellington (English (UK)): R2 #~ is missing the secondary \ and | symbols. OR, better, the other copies of the #~ unduly have them. The actual English (UK) layout doesn't place backslash and pipe in the tertiary and quaternary layers for the movable keycap — it's an addition by Microsoft's implementation.
Mentioned previously, this isn't changing. The AltGr \| symbols are applied to keys which would be used in an ANSI/HHKB layout.
Waterloo (English (US, international)): the S keycap should have § in the upper right corner.
Corrected in latest draft.
Uhlan (combined Polish and Lithuanian): the difference between lowercase tertiary legends (Polish) and uppercase quaternary (Lithuanian) comes off as odd.
Revised alongside other layouts that simultaneously display (1) multiple languages and (2) AltGr characters for one of the languages. Lithuanian characters are shown in red and remain in the top-right corners to help further distinguish them from the yellow Polish AltGr characters.
Murat (Spanish and Italian):
- Spanish (Spain): 1!| , 2"@ , 4$~ are missing.
- Italian: supports Italian (141), but that layout was deprecated long ago in favor of Italian (142). The curly braces are missing (but don't fix that! Go 142 instead).
- Make a note stating that this set supports Spanish (Spain), not Spanish (Latin America)... or Iberoamerican Spanish, for that matter.
All AltGr characters were omitted from this kit to avoid compatibility conflicts across Italian, Italian 142, Italian Apple, Spanish, and Spanish Apple layouts. Description of image amended to note that this supports European Spanish.
Marie Louise (French Apple and Belgian): if this is intended to support Belgian on Windows, there are too many errors. Looks like it's meant for Apple only, but it's not clear from the description. I can't find Belgian on Windows support in other kits.
Significant corrections were made to this kit.
João VI (Portuguese):
- 4$ should be 4$§ ; 7/ and 0= are missing the curly braces.
- Make a note that this set supports Portuguese (Portugal), not Portuguese (Brazil).
Set notes that it is implemented for European Portuguese. Additional optional keys for 4, 7, and 0 are now provided.
Bernadotte (Danish, Norwegian, Swedish/Finnish, "etc."):
- Plain M (without µ) is missing (Nordic layouts in general don't use it).
- Danish is missing ◌́◌̀| and <>\
- Estonian (if supported) is missing '?\ , Ä◌̂ , '½ , <>|
- Faroese (if supported) is missing ◌́◌̀| , <>\ , Ø◌̂ , Å◌̈ , Ð◌̃
- Icelandic — too many keys missing; it's obvious it's not supported.
- Swedish/Finnish: <>| and +?\ are missing.
Multiple corrections here. Faroese and Estonian are both supported, but with some AltGr legends missing. An additional M key without mu was added.
Icelandic is not supported as it has too many differences from these layouts to fit into a single kit.
Act of mediation (Swiss):
- R3 "!] - note the first character is supposed to be ◌̈ , not a quote sign.
- 4ç° and 5%§ : the degree and section signs are not part of the Swiss layout (they're part of MS' ****ty implementation).
- Note the placement of | and ¦ (again, a problem of MS' ****ty implementation).
The double-quote was indeed incorrect and has been replaced with an umlaut.
The remaining notes here may be implementation-specific, but they appear to be correct according to both Apple's and Microsoft's implementations. Things like the swapped pipe/bar characters are staying as-is since only Linux seems to follow the official government-endorsed standard.
Chateauguay (Canadian BILINGUAL):
- The corner key is #|\ — the forward slash is out of place there.
- 1! is missing ± in the tertiary corner.
- 2"@ - check those corners!
- Missing tertiaries from 3/ up to =+ , all R3 keys from O onwards and R2 keys from ;: onwards.
- R1 «»Ù is actually «»°. Tertiaries missing from M onwards.
This has received multiple adjustments. It is now a set combining both Canadian Multilingual and Canadian French. CF legends that differ from CM are shown in red. AltGr legends for CM are provided where space allows.
Other changes have occurred with the remaining alpha kits. The Doppelkaiser kit replaces Illyria; it is now a combined South Slavic / Hungarian kit in much the same pattern as Chateauguay and Uhlan.
