The problem is: 1. I have tex file with which calls a macro with argument that has characters U+5d5 and U+5bc. 2. Macro passes argument further to lua code. When it gets there characters have turned to U+fb35. 3. When the lua code then compares the U+fb35 with xml file that has the original forms U+5d5 and U+5bc it of course fails. So, the problem is that there is this phase 2 that has not always happened. If possible I would like to turn it off somehow. Of course I could try to write some workaround code to countermeasure this substitution or what it should be called. But that could be complicated and lead to more problems. Simo PS: I attached my result of the test case in case this is problem with my setup. Compiled with ConTeXt MkIV 2012.09.25 21:44.
