Collaboratively edited documentation for Indic font developers

One of the integral building blocks for providing multilingual support for digital content are fonts. In current times, OpenType fonts are the choice. With the increasing need for supporting languages beyond the Latin script, the TrueType font specification was extended to include elements for the more elaborate writing systems that exist. This effort was jointly undertaken in the 1990s by Microsoft and Adobe. The outcome of this effort was the OpenType Specification – a successor to the TrueType font specification. ...

Hyphenation in web

This is a follow up of a 4 year old blog post about hyphenation. Hyphenation allows the controlled splitting of words to improve the layout of paragraphs, typically splitting words at syllabic or morphemic boundaries and visually indicating the split (usually with a hyphen). I wrote about how a webpage can use Hyphenator javascript library to achieve hyphenation for a text with ‘justify‘ style. Along with the hyphenation rules I wrote for many Indian languages, this solution works and some websites already use it. The Hyphenator library helps to insert Soft hyphens in appropriate positions inside the text. ...

Cross Language Approximate Search on Indic Languages- A demo

A demo of cross language approximate search in Indic text: The Malayalam word സാമ്പാര്‍ is compared against a paragraph from http://ml.wikipedia.org/wiki/Sambar. In the bottom half, words marked in yellow color are search results. You can see that a Kannada word ಸಾಂಬಾರ್‍ is matched for Malayalam word. And that is why this is called cross-language. The inflections of the words സാമ്പാര്‍ – സാമ്പാറും, സാമ്പാറു etc are also found as results. This is the kind of search we need in Indic languages, not just the letter by letter comparison we do for English. ...

Identifiers In Indic Languages

Recently, while preparing a critique for IDN Policy for Malayalam language prepared by CDAC, I noticed that ICANN does not allow control characters in the domain names. Sometime back I noticed Python 3 identifiers also does not allow control characters in the Identifiers. This blog post attempts to analyze the issue by looking at the Unicode and ICANN specifications about these special characters. Apart from the existing characters in Indic languages, Zero width Joiner and Zero width non joiners are widely used in Indic languages to control how the ligatures are formed. For some samples on how they are used, refer the wikipedia links. Being control characters and invisible characters, they are often removed while doing normalization , particularly before doing a string comparison, or collation (sort). ...
