regex - Range in reverse order? -

-

the following regex failing on me;

[aa][æ-åÆ-Å].*

but regex not failing

[aa][v-zv-z].*

it when æ-å used (danish carachters). im puzzled why?

the error getting it

parsing "[aa][æ-åÆ-Å].*" - [x-y] range in reverse order.

æ character code 145, while å character code 134, you're saying give me characters between character codes 145 , 134 doesn't work since lower bound greater upper bound. same true Æ Å.

here's 1 chart of character codes can determine regex need create instead:
