Why oṃ.com is the correct form
ओं
The name in its original Devanagari form. ओं → Oṃ. Sanskrit Oṃ is written in Devanagari as ओं · IAST transliteration maps each Devanagari vowel and consonant to a Latin equivalent · Macrons mark long vowels (ā, ī, ū); dots beneath consonants mark retroflex articulation (ṭ, ḍ, ṇ, ṣ)
OM
Stripped of its identity, the name was reduced to plain Latin letters. The original orthography — stress, length, breathing — was erased by systems that only understand A-Z.
Oṃ
The Unicode restoration recovers what ASCII destroyed. This is philological accuracy — not decoration. The domain encodes to Punycode, but the browser displays the truth.
oṃ.com → xn--o-opm.com
The non-ASCII characters in Oṃ are encoded while the ASCII remains visible. To the DNS, it is Punycode. To humanity, it is Oṃ.
How om becomes Oṃ
| Step | ASCII | Unicode | Type | Scholarly Note | |
|---|---|---|---|---|---|
| 01 | o | → | O | Same | Same, capitalized |
| 02 | m | → | ṃ | Special | M with dot: anusvara |
Why Oṃ is classified as Tier-2 Basic
The Sanskrit form ओं preserves neither stress nor length in this Unicode restoration. This makes it a single-tier Tier-2 Basic name — still a scholarly step above plain ASCII, but without the distinctive phonetic features that define higher tiers.
