i provide you with a javascript text editor that automatically removes all k/K letters as you type and changes it to unicode 0915 glyph. you basically integrate this for the database / dynamic text editor areas and for the database / dynamic non-text editor areas you change via some database script and bad letter / word filter.

then for the static areas / user interface and those error 404 machine code messages etc you change the language file etc, removing all k/K letters and putting unicode 0915 glyph.

there could be things that are not like above, thus there could be some variables, functions and constants on the program/code that require intervention.

the work should also work with other major extensions.

i would prefer the work to be completed urgently though this is dependent on the experience and qualification.

could you say how much this work will cost and include your portfolio.
