1) Special keys & symbols

• * → ं (anusvara)
• ** → ँ (chandrabindu)
• . → । (danda)
• \\ → ् (halant/virama)
• 0–9 → ०–९ (Nepali digits)
• ri^ → ् + र + ि (रि before a cluster)
• rr → र्‍ (repha with ZWJ)
• rri → ऋ  |  rree → ॠ
• {…} → English passthrough
• [ … ] → “smart tweaks” OFF for that span
• / → cluster/syllable break (stop auto-joining)

2) Independent vowels (word start / after space)

Note: ri^ is a composition helper (र् + ि) used inside clusters, not a standalone vowel.

3) Consonant families (with all vowel combos)

How the combos work

• Bare consonant (with halant): k → क्
• Inherent “a”: ka → क
• Long “aa”: kaa → का
• “i”: ki → कि   |   “ee”: kee → की
• “u”: ku → कु   |   “oo”: koo → कू
• “ri”: kri → कृ
• “e/ai/o/au”: ke/kai/ko/kau → के/कै/को/कौ

Core stops, nasals, etc.

ka → कkha → खga → गgha → घnga → ङ ca → क (alias)cha → चchha → छja → जjha → झ yna → ञTa → टTha → ठDa → डDha → ढNa → ण ta → तtha → थda → दdha → धna → न pa → पpha → फba → बbha → भma → म ya → यra → रla → लva/wa → व sa → सsha → शSha → षha → ह

Conjuncts / special consonants

ksha → क्ष xa → क्स gya → ज्ञ Nepala → नेपाल qa → क (alias)

Using the family pattern, you also get kshaa, kshi, kshee, kshu, kshoo, kshri, kshe, kshai, ksho, kshau…

4) Smart-tweak words (autocorrections)

When Smart tweaks is ON, these exact words auto-adjust before mapping:

cha/chu/chha → chha/chhu/chha ma → ma aba → aba nam → naam ram → raam pani → pani lai → laaii pai → paaii dai → daaii bhai → bhaaii

General heuristics

• Word ending in y → becomes …ree before conversion
• cha/che/chu/cho after c+h → upgraded to chh… forms
• Final i after a non-vowel → becomes ee
• Safety exceptions (…ahh, …ank, …anh, …anr, …nard, …nart) left untouched

Use [ … ] to bypass these for a span, or / to force a break.

5) Special case & quick examples

Hard-wired: gyo → ग्यो (ग + ् + य + ो)
