Too many OEM keys error

[TrialDragon]

Hiya, when trying to build my layout:

# kalamine keyboard layout descriptor
name        = "futhorc"  # full layout name, displayed in the keyboard settings
name8       = "futhorc"         # short Windows filename: no spaces, no special chars
locale      = "en"             # locale/language id
variant     = "futhorc"         # layout variant id
author      = "nobody"         # author name
description = "modern FUÞORC layout"
url         = "https://OneDeadKey.github.com/kalamine"
version     = "1.0.1"
geometry    = "ISO"

I’m afraid we don’t support non alphanumeric layout yet

[wismill]

@Geobert In such case it should fallback to the Qwerty VK_s, as there is currently no support for transliteration.

[notpushkin]

I’ve made a tiny hotfix that might help. In kalamine/generators/klc.py, add this in klc_virtual_key after if shifted.isascii() ...:

cyr_lat = dict(zip(
    'йцукенгшщзфывапролэячсмтьЙЦУКЕНГШЩЗФЫВАПРОЛДЯЧСМИТЬ',
    'qwertyuiopasdfgjklzxcvbnmQWERTYUIOPASDFGHJKLZXCVBNM',
))

if shifted in cyr_lat:
    print('cyr_lat:', shifted, cyr_lat[shifted])
    return cyr_lat[shifted]

Replace the Cyrillic letters with your characters. (This will only work if you don’t use Latin characters at all.)
