The following Nativization conventions are automatically applied when Malayalam is the Target Script.
Features of Malayalam Script
Chillu Characters are a unique feature to Malayalam Script.
In Malayalam, the Virama (Chandrakala) serves two purpose, as an Inherent Vowel Killer, and to denote half-u (Samvrutokaram). Hence, to avoid confusion, certain consonants have special forms called "Chillu" do denote the pure consonant. Modern Malayalam uses 5 chillu forms for ന, ണ, ല, ള, ര . Historically, other consonants also had chillu forms., but they are not in current usage. [The Converter uses ʼ character is used to distinguish chillus from their Virama forms in other scripts during transliteration. The distinction is necessary to preserve the semantics ]
മനുഷ്യന് - manuṣyanŭ (Transcription) (Meaning: To the Man)
മനുഷ്യന് - manuṣyan (Transcription) (Meaning: Man)
Additionally, Half-u vowel can also be represent as combination of <vowel sign u> and <virama>, which does not lead to any confusion. In fact, Ancient Tamil used this method to represent the half-u. In Modern Tamil <vowel sign u> represents both u and half-u
തേക്കു് - tēkkŭ as opposed to തേക്ക് (tēkk).
However, this is practice is not widely spread, & the ambiguous way of representing the half-u is more popular.
Vowel Sign Au
Malayalam has two forms for Vowel Sign Au. The Ancient form, which has vowel markers on both side of the Consonant കൌ <<kau>>. This is encoded in Unicode as ൌ U+0D4C (Malaylam Vowel Sign Au), however this is an archaic and obsolete method. The Modern form has only one vowel marker, to the right side of the consonant കൗ <<kau>>. This is encoded as ൗ U+0D57 (Malayalam Au Length Mark).
Classical Malayalam Orthography
The Original Malayalam script was a very complex script with ligating vowel signs and used conjuncts extensively. The script was scrambled in the 80's by the Kerala Govt. , to fit the mechanical typewriter. The usage of old script has not completely done away with, it is still used occasionally. To use Classical Orthography, use fonts such as Racana or e - Malayalam OTC. Classical Orthography has more conjuncts, ligated Vowel Sign U/UU, and ligated Vowel sign vocalic R, and also uses the Repha. There are currently two fonts for the Classical Script, e-Malayalam OTC and the Rachana Font. But only the e-Malayalam OTC has support for the Repha.

Transliteration of Malayalam Script
Malayalam script is unique, in the sense it inherits both Dravidian and Indo-Aryan Characteristics into its script. In uses Dravidian-style spelling when writing native words, grammatical and endings (Such as using /k/ for both /k/, /g/ similar to that of Tamil) , and Indo-Aryan based spelling (such as using distinct /k/ /kh/ /g/ /gh/ letters) for its Loan Words. Thus, formal knowledge of Malayalam [or at least Tamil] is inevitable to read/transcribe the Malayalam Script according to its native phonetics.
One needs to perform Intelligent Transcription of Malayalam must consider all these factors, to perform the Transcription accordingly.

Display Issues with Chillus
Previously, Chillus were encoded in Unicode by combiningg the Virama forms of the consonants with the Zero Width Joiner (ZWJ). Due to various issues, Separate codepoints were allocated for the Chillu Characters. - ൺ ൻ ർ ൽ ൾ ൿ - These are known as "Atomic Chillus". Their use not is not widespread, and most of the old Unicode fonts don't support Atomic Chillus. Code2000, e - Malayalam OT are a few fonts which support Atomic Chillus. They are also supported in Kartika on Windows Vista/7.

Instead of the Modern Au sign, the Archaic sign is used. (e.g) കൌ
