The Ol Chiki script was invented by Pandi Raghunath Murmu in the 1920s to provide Santali, spoken by around 6 million people, with a dedicated script, instead of the Latin, Bengali, Devanagari, and Odia that had been and still are used. Ol Chiki is primarily used for the southern dialect of Santali, and has received some official recognition. It has been used for other Munda languages.

The Ol Chiki script is an alphabet. Both consonants and vowels are indicated by letters. See the table to the right for a brief overview of features for the Santali language.
Ol Chiki is mostly a simple and small orthography. There are no combining characters, and no symbols. The script has no case distinction.
Ol Chiki runs left to right in horizontal lines.
Words are separated by spaces.
Santali has 23 consonant letters. Consonants can be aspirated by forming a digraph with a special aspiration letter.
There are 6 basic vowel letters, and 3 digraphs, where an existing vowel letter is followed by a dot. All vowels can be nasalised and lengthened by modifiers.
Ol Chiki has a unique way of handling syllable-final consonants. Four of the voiced stops are typically pronounced unreleased, and unvoiced if they don't appear before a vowel. Where the full value of the letter should be retained, this can be indicated using a modifier called ahad. Another hyphen-like modifier,phaarkaa, applies the reduction before a vowel, when needed (for example for certain verb forms).
Ol Chiki has native digit shapes.
Block-specific danda and double-danda are used as sentence and section dividers. Otherwise, most of the punctuation is ASCII.
Distinctive characteristics: an alphabet surrounded by abugidas; modifiers for voiced stops at word boundaries; no combining characters.

Santali can have successive vowels without intervening consonants, but they are not diphthongs such as those that combine with a glide at the end.
The following reprour are non-native or allophones. Source Wikipedia.
|stops||p b||t d||ʈ ɖ||c ɟ||k ɡ|
|aspirated||pʰ bʰ||tʰ dʰ||ʈʰ ɖʰ||cʰ ɟʰ||ɡʰ|
The aspirated stops occur primarily, but not exclusively, in Indo-Aryan loanwords.wl,#Phonology
ɳ only appears as an allophone of n before ɖ.wl,#Phonology
A typical Munda feature is that word-final stops are "checked", i. e. glottalised and unreleased.wl,#Phonology

The standard vowel sounds for Santali are written as follows.
Three additional vowel sounds are represented using ᱹ [U+1C79 OL CHIKI GAAHLAA TTUDDAAG],
ᱚᱹ [U+1C5A OL CHIKI LETTER LA + U+1C79 OL CHIKI GAAHLAA TTUDDAAG] is rarely used, and the phonetic difference between it and ᱚ [U+1C5A OL CHIKI LETTER LA] is not clearly defined, but the ALA-LOC transcription page says that it has a lower pitch. The phonemic difference between the two may be only marginal.rp,9
Nasalisation of vowels is indicated using ᱸ [U+1C78 OL CHIKI MU TTUDDAG],rp,9 eg. ᱦᱟᱸᱰᱮ
When the letter is followed by ᱹ [U+1C79 OL CHIKI GAAHLAA TTUDDAAG] a separate Unicode character is used, rather than adding the two characters. That character is ᱺ [U+1C7A OL CHIKI MU-GAAHLAA TTUDDAAG],rp,9 eg. ᱵᱮᱺᱫᱤ
To indicate a prolonged vowel sound, ᱻ [U+1C7B OL CHIKI RELAA] is used,rp,9 eg. ᱢᱚᱹᱬᱮᱻ ᱢᱚᱸᱻᱦᱟ
There are no special forms for consonant clusters in Santali.

Sounds listed as 'infrequent' are allophones, or sounds used for foreign words, etc.
ᱵ [U+1C75 OL CHIKI LETTER OB] when not followed by a vowel.
ᱫ [U+1C6B OL CHIKI LETTER UD] when not followed by a vowel.
ᱡ [U+1C61 OL CHIKI LETTER AAJ] when not followed by a vowel.
ᱜ [U+1C5C OL CHIKI LETTER AG] when not followed by a vowel.
Four voiced stops are pronounced unvoiced and unreleased when they are not followed by a vowel, especially in word-final position.
|ᱵ [U+1C75 OL CHIKI LETTER OB]||b||→||p̚||eg. ᱩᱵ|
|ᱫ [U+1C6B OL CHIKI LETTER UD]||d||→||t̚||eg. ᱢᱮᱫ|

|ᱜ [U+1C5C OL CHIKI LETTER AG]||ɡ||→||k̚||eg. ᱫᱚᱜ|
Where the voicing needs to be maintained, ᱽ [U+1C7D OL CHIKI AHAD] is added, eg.
In the opposite situation, where a voiced consonant is used before a vowel but you want to allow the devoicing, put ᱼ [U+1C7C OL CHIKI PHAARKAA] before the vowel.rp,10 For example, see this verb form: ᱢᱮᱱᱟᱜᱼᱟ
Aspirated consonant sounds are indicated using ᱷ [U+1C77 OL CHIKI LETTER OH] after the consonant,fp,2 eg. ᱡᱷᱚᱛᱚ ᱛᱷᱚᱲᱟ
The Ol Chiki Unicode block has no characters with the general category of Symbol.

bidi_class properties for characters in the Santali orthography described here.
This section brings together information about the following topics: writing styles; cursive text; context-based shaping; context-based positioning; baselines, line height, etc.; font styles; case & other character transforms.
You can experiment with examples using the Ol Chiki character app.
Santali text is not cursive (ie. joined up like Arabic), however there is some ligation in hand written text which doesn't occur in printed content.
The orthography has no case distinction, and no special transforms are needed to convert between characters.
Since there are no combining marks or decompositions, grapheme clusters correspond to individual characters.
Question: Should nasalisation or vowel extension dots be handled like combining characters, ie. form a grapheme with the preceding character?
Word units are separated by spaces.
Paired words may be separated by ᱼ [U+1C7C OL CHIKI PHAARKAA], eg. ᱥᱩᱡᱷᱼᱵᱩᱡᱷ sujʰ-bujʰ
Santali uses mostly ASCII punctuation, but also some Indic punctuation from the Santali block.

; [U+003B SEMICOLON]
: [U+003A COLON]
|section||᱿ [U+1C7F OL CHIKI PUNCTUATION DOUBLE MUCAAD]|
The ASCII full stop is not used, since it creates confusion with other dots in the orthography, therefore ᱾ [U+1C7E OL CHIKI PUNCTUATION MUCAAD] is the main sentence delimiter.rp,11
᱿ [U+1C7F OL CHIKI PUNCTUATION DOUBLE MUCAAD] is used at the end of a paragraph or some other block of text.
Observation: Samples in the Unicode proposals suggest that the mucaad and double mucaad punctuation is preceded by a space.
Santali commonly uses ASCII parentheses to insert parenthetical information into text.
Santali texts use quotation marks around quotations. Of course, due to keyboard design, quotations may also be surrounded by ASCII double and single quote marks.

Observation: Lines appear to be broken at word boundaries.
Show (default) line-breaking properties for characters in the modern Santali orthography.
Observation: All but one of the samples in the Unicode submission document are fully justified. Mostly, the justification is achieved by stretching inter-word spacing, however some words also have the space between characters stretched.
This section looks at ways in which spacing is applied between characters over and above that which is introduced during justification.
Santali uses the so-called 'alphabetic' baseline, which is the same as for Latin and many other scripts.
You can experiment with counter styles using the Counter styles converter. Patterns for using these styles in CSS can be found in Ready-made Counter Styles, and we use the names of those patterns here to refer to the various styles.
Santali Wikipedia pages use numeric styles.
The numeric style is decimal-based and uses these digits.
A range of prefixes and/or suffixes is used in Wikipedia. They include a simple period, parentheses on both sides, and no mark.
