Trouble with transliteration in slug caused by hardcoded charmap in craft.js I've been struggling with automatic slug generation in Czech language: there are letters such as "š" or "č" and Craft has a charactere map hardcoded in craft/app/resources/js/craft.js, resp. craft/app/resources/js/compressed/craft.js, which tells craft to convert "š" to "sh" and "č" to "zh" for instance. 

In Czech language that is not necessary; it's rather bad behavior which I need to change. Letter "š" should become "s" etc. 

Is there any systematic way how to configure this character map? 

I technically have no problems with rewriting the table, although that solution might either cause errors with automatic updates or my changes could get rolled back with every update - neither being good. 

PS: This issue is NOT related to the same thing as here: How to transform German umlauts when creating slugs? - the described behavior is in place even with "limitAutoSlugsToAscii == 1"

UPDATE:

In case this question was not resolved yet or had no solution, here is a minified charmap which works as a hotfix to Craft issues with Czech slugs: http://pastebin.com/pc6etBFu

It works as a drop-in replacement for the same map in craft/app/resources/js/compressed/craft.js. My current version of craft is Craft Pro 2.3.2643
You can try using my plugin, which will overwrite the character map in craft.js by applying the customAsciiCharMappings setting:

Tell me if it's working for you.
