If a consonant has two subscript forms and the choice affects the meaning, the form typically used for syllable-final consonants will be encoded with SAKOT, and the other form will have its own code point. There are 7 consonants which have different subscript forms in this way, namely {{lang|nod|ᩁ}} RA, {{lang|nod|ᩃ}} LA, {{lang|nod|ᨷ}} BA, {{lang|nod|ᩈ}} HIGH SA, {{lang|nod|ᨾ}} MA, {{lang|nod|ᨳ}} HIGH RATA, and {{lang|nod|ᨻ}} LOW PA.

The latter word is also written as {{lang|nod|ᨴᩮ᩠ᨷ}}.
The Lao-style consonant conjunct {{lang|lo|ᨲ᩠ᨳ}} (encoded as &lt;U+1A32 HIGH TA, U+1A60 SAKOT, U+1A33 HIGH THA&gt;) looks as though it is {{lang|lo|ᨲᩛ}} encoded as &lt;U+1A32 HIGH TA, U+1A5B SIGN HIGH RATHA OR LOW PA&gt;. The shape of U+1A5B depends upon the consonant it is subscript to.
 
The dependent vowel of words like {{lang|nod|ᨯᩬᨠ}} 'flower' is encoded by the special vowel &lt;U+1A6C SIGN OA BELOW&gt;; one should not use the sequence &lt;U+1A60 SAKOT, U+1A4B LETTER A&gt; There is also an encoded dependent vowel for words like Tai Khuen, Tai Lue and Lao words such as {{lang|kkh|ᨶ᩶ᩭ}}, namely U+1A6D SIGN OY. This vowel is not encoded as &lt;U+1A6C SIGN OA BELOW, U+1A60 SAKOT, U+1A3F LOW YA&gt; (which is what Northern Thai uses for the corresponding words; nor is it the sequence &lt;U+1A60 SAKOT, U+1A40 HIGH YA&gt;<ref name=N3207R/>⁠{{rp|at=Section&nbsp;5}}

Superscript consonants are encoded independently of the base consonants. Some characters serve both as superscript consonants and in other roles, and are therefore discussed further in this section.
[[Anusvara|Niggahita]] and is encoded as U+1A74 MAI KANG. Superscript WA is not encoded separately. It is encoded as MAI KANG. For example, Tai Khuen {{lang|kkh|ᨯ᩠ᨿᩴ}} ({{IPA-|shn|deu|IPA}}) is encoded as &lt;U+1A2, DA, U+1A60 SAKOT, U+1A3F LOW YA, U+1A74 MAI KANG&gt;. For the purposes of character sequencing, it is generally treated as a vowel.
 
Superscript cluster-initial NGA is encoded as U+1A58 MAI KANG LAI. Note that Lao generally uses the same glyph for MAI KANG LAI and U+1A59 SIGN FINAL NGA.
Line 206 ⟶ 207:
U+1A62 MAI SAT serves three roles - it is a vowel, a final consonant, and a vowel shortener.
 
Choosing the encoding of the superscript form of RA and the vowel killers was difficult. In the 1940's1940s the Tai Khuen wrote the consonant and the vowel killer the same way. The proposers of the encoding made enquiries and were told that the glyphs were still the same and therefore encoded them both as U+1A7A RA HAAM. It was then learnt that the Tai Khuen had changed the glyphs of the vowel killer, and a new character U+1A7C KARAN was added for the Tai Khuen style of the vowel killer. Some Northern Thai writers prefer to use U+1A7C as the vowel killer, and indeed the use of its glyph is not unknown in Northern Thai handwriting.
 
==Special Consonants==
The special forms {{lang|nod|ᩓ}} and {{lang|nod|ᩕ}} are encoded by the code points U+1A53 and U+1A55 respectively.
 
If the glyphs of U+1A36 NA and U+1A63 SIGN AA would be side by side they are written as the ligature {{lang|nod|ᨶᩣ}} rather than as two separate glyphs {{lang|nod|ᨶ&zwnj;ᩣ}}. They are written as a ligature even if the NA has a subscript consonant or a non-following mark attached. Examples: {{lang|nod|ᨾᨶ᩠ᨲᩣ}} ({{IPA-|nod|man taː|IPA}}, encoding &lt;U+1A3E MA, U+1A36 NA, U+1A60 SAKOT, U+1A32 HIGH TA, U+1A63 SIGN AA&gt;) and {{lang|nod|ᨶᩮᩢᩣ}} ({{IPA-|nod|nau|IPA}}, encoding &lt;U+1A36 NA, 1A6E SIGN E, U+1A62 MAI SAT, U+1A63 SIGN AA&gt;). Subscript NA and SIGN AA do ''not'' similarly ligate, e.g. {{lang|nod|ᩉ᩠ᨶᩣ}} (({{IPA-|nod|naː|IPA}}), encoded &lt;U+1A49 HIGH HA, U+1A60 SAKOT, 1A36 NA, U+1A63 SIGN AA&gt;)
 
The geminate consonant {{lang|nod|ᩔ}} is encoded separately because the word {{lang|nod|ᩅᩥᩈᩮ᩠ᩈ}} ({{IPA-|nod|wiseːt}}, encoding &lt;U+1A45 WA, U+1A65 SIGN I, U+1A48 HIGH SA, U+1A6E SIGN E, U+1A60 SAKOT, U+1A48 HIGH SA&gt;) has an appearance very different from {{lang|nod|ᩅᩥᩔᩮ}}, but one may have occasion to fold the final syllable to &lt;HIGH SA, SAKOT, HIGH SA, SIGN E&gt;. Indeed, in 2019 to 2020 there was a campaign to establish the latter as its standard spelling.
 
By contrast, the geminate consonant {{lang|nod|ᨬ᩠ᨬ}} is encoded as the conjunct &lt;U+1A2C NYA, U+1A60 SAKOT, U+1A2C NYA&gt;, even though some of its glyphs may resemble the hypothetical conjunct {{lang|nod|ᨱ᩠ᨬ}} &lt;U+1A31 RANA, U+1A60 SAKOT, U+1A2C NYA&gt;.
Line 243 ⟶ 244:
The 'onset letters' are consonants, independent vowels or special symbols. The consonants in a group are ordered according to the order in which they are sounded or used to be sounded.
 
Example: {{lang|nod|ᨻᩩᨴ᩠ᨵ}} ({{IPA-|nod|put thaʔ}})
:onset letter: {{lang|nod|ᨻ}}
:pure vowel: {{lang|nod| ᩩ}}
Line 253 ⟶ 254:
The encoding is &lt;U+1A3B LOW PA, U+1A69 SIGN U, U+1A34 LOW TA, U+1A60 SAKOT, U+1A35 LOW THA&gt;
 
Example: {{lang|nod|ᨻᩕ}} has a single consonant sound {{IPA-|nod|pʰ}}, but formerly had 2 sounds, namely those of {{lang|nod|ᨻ}} and then {{lang|nod|ᩁ}} as in central Thai. This word is encoded as &lt;LOW PA, MEDIAL RA&gt;.
 
Apart from MEDIAL RA, the order of the consonant glyphs is the same as the order of the sounds. In most cases MEDIAL RA is the last consonant but the WA of /ua/ and the LOW YA of /ia/ follow MEDIAL RA.

Outside Northern Thailand, the MAI KANG in the symbol for /am/ is written on the SIGN AA component. In Northern Thailand, it is positioned variously – on the consonant, on the SIGN AA and between them. The Unicode Consortium refused a special character for the combination. The word {{lang|nod|ᨷᩴ᩠᩵ᨾᩣ}} ({{IPA-|nod|bɔːmaː|IPA}}) should not appear to have the same vowel as {{lang|nod|ᨲ᩵ᩣᩴ}} ({{IPA-|nod|tam|IPA}}). The combination for /am/ is therefore encoded as &lt;U+1A63 SIGN AA, U+1A74 MAI KANG&gt;. The word {{lang|nod|ᨷᩴ᩠᩵ᨾᩣ}} is encoded as &lt;U+1A37 BA, U+1A74 MAI KANG, U+1A75 TONE-1, U+1A60 SAKOT, U+1A3E MA, U+1A63 SIGN AA&gt;. The word {{lang|nod|ᨲ᩵ᩣᩴ}} is encoded as &lt;U+1A32 HIGH TA, U+1A75 TONE-1, U+1A63 SIGN AA, U+1A74 MAI KANG&gt;. The combination for /am/ with SIGN TALL AA is encoded as &lt;U+1A64 SIGN TALL AA, U+1A74 MAI KANG&gt;.
 
U+1A5A SIGN LOW PA is a special case; the Tai Lue word {{lang|khb|ᨣᨽᩚ}} ({{IPA-|khb|kap phaʔ|IPA}}) is encoded as &lt;U+1A23 LOW KA, U+1A3D LOW PHA, U+1A5A SIGN LOW PA&gt;.<ref name="N3207R"/>{{rp|at=Section 4}}
