Martin Hosken, Discussion of Mro Dandas
Mru (or Mro) is a Tibeto-Burman language spoken primarily in Bangladesh with a few speakers in India. According to the Unicode script proposal, literacy levels for this script among the 100,000 Mro exceed 80%.p Education in the script is available up to grade 3.@Scriptsource,https://scriptsource.org/cms/scripts/page.php?item_id=script_detail&key=Mroo
The script was invented by Menlay Murang (or Manley Mro) in the 1980s. Mro folklore says that an earlier script was sent with a cow by the god Turai, but the cow became hungry and ate the book it was carrying. Murang aimed to restore a writing system to the Mro people.
The Mro script is an alphabet. Both consonants and vowels are indicated by letters, and the script is mostly quite straightforward. See the table to the right for a brief overview of features for the orthography used to write the Mro language.
Mru text runs from left to right in horizontal lines. Words are separated by spaces. The orthography is unicameral.
Mru uses 25 consonant letters, but 6 of those are duplicates, representing the same sound as another letter. There are no combining marks or special forms for consonant clusters. Syllable medial and final consonants are represented using ordinary consonant letters.
The Mro orthography is an alphabet where vowel sounds are written using just 7 dedicated letters, and one digraph (which combines 2 of the 7).
Mru has no prebase glyphs. or circumgraphs. Multiple vowels may sometimes be used together. There are no letters or diacritics for tone, nasalisation, or vowel length.
Standalone vowel sounds are written using the normal vowel letters.
Punctuation is mostly that used for the Latin script, but Mro includes 2 native punctuation marks resembling dandas.
Mro has its own set of digits.
Line-breaking and justification are primarily based on inter-word spaces.
The following represents the general repertoire of the Mru language.

Mru is not a tonal language.
The following table summarises the main vowel to character assigments.
ⓘ represents the inherent vowel. Diacritics are added to the vowels to indicate nasalisation (not shown here).
For additional details see vowel_mappings.
The standard vowel sounds for Mro are written using the following characters.
Mro doesn't indicate tones, nasalisation or long vowels.
No special mechanism is used to show the absence of a vowel.
Standalone vowel sounds are simply represented using ordinary vowel letters.
No special mechanisms or rules are employed to indicate consonants that are not followed by a vowel. The vowel letter is simply omitted.

For additional details see consonant_mappings.
Several consonants can be written with more than one letter. Typically the first letter in the list above is used for most words, but a few words use the following letter instead. Click on the letters above for examples.
Some sound sequences can be abbreviated to a single letter (see abbrev).
Mru syllables can begin with a consonant cluster, but they are just written using the relevant letters.
Syllable-final consonants are also just represented by ordinary letters.
Mru has no conjunct forms for consonant clusters.
Consonant gemination doesn't appear to be common in Mru.

Sounds listed as 'infrequent' are allophones, or sounds used for foreign words, etc.
Mru has its own set of digits, with a decimal base.
Mru text is written horizontally, with lines that flow from top to bottom.
You can experiment with examples using the Mru character app.
There appears to be no contextual shaping of letters, and there are no combining characters in Mro.
In Mru text, there are no combining marks, and each letter is a unit of text that corresponds to a grapheme cluster.
Words are separated by spaces.
See type samples.
Basic phrase and section boundaries in Mru use ASCII punctuation.
Observation: The sources are not very clear about the relationship between the 2 danda-like characters. It may be that one represents a comma like pause and the other a sentence-final punctuation. Occasionally, ASCII punctuation can also be found in the same text for each of those functions.
Mru commonly uses ASCII parentheses to insert parenthetical information into text.
Mru texts may use quotation marks around quotations. Of course, due to keyboard design, quotations may also be surrounded by ASCII double and single quote marks.

|’ [U+2019 RIGHT SINGLE QUOTATION MARK]
Two consonant letters may be used to represent an abbreviated sound sequence.
Compare the following pairs.
The principal line-break opportunities are inter-word spaces.
Mru uses the 'alphabetic' baseline.
