Cyrillic characters don't work

Regular expressions with cyrillic characters (e.g. [А-Я]{1,5}[а-я]{5,10}) don’t work in the latest version. The last version it used to work in is 0.4.6.

I’m leaning towards @michaelficarra in that the default range should be respected for predefined sets, but for custom non-negated sets like in the OP (e.g. [А-Я]{1,5}[а-я]{5,10}), could ignore the default range

@michaelficarra if it was restricted by someone to a-f then it was done on purpose. For a-f it can be easily found: letters for hexadecimal numbers. If there goes some y or z then it’s gonna blow up. The regexp itself is not always something you write into code and control. The randexp.js instance however is. I believe explaining that as “the default range of generated characters applies to whole regexp” is also simpler and more consistent than “the default range applies only to ‘open’ sets and negated groups, but not for predefined ranges”. And I don’t understand what’s the problem with one line of code randexp.defaultRange.add(0, 65535); if you want Chinese, Russian and others.
