This is by no means a fully comprehensive guide to adding Khmer language to your website, and there are many ways to achieve the same results, but from our experience we have found this method to work very simply. You will be able to get going with your multi-lingual or Khmer script only website much quicker than previously.
It is only in the last few years that Khmer has gained unicode support, as previously the native Cambodian language was unsupported on most computers and in most software. Before Khmer Unicode was created, getting Khmer to work required that you use a set of custom fonts called “Limon”. Sometimes you still find documents containing text using this – Limon isn’t compatible with unicode though and it doesn’t work on websites. If you face this situation then you will need to have the text converted to unicode before it will be usable in WordPress.
Similar difficulties are encountered using recent versions of Adobe Photoshop and Illustrator to produce Khmer language artwork. It used to be very difficult but with widespread adoption of unicode it is much easier these days.
