[icu-support] Expressing Word Boundaries in Transformation Rules

[Daniel Y. <lo...@ge...>]

Greetings,

I'm having trouble writing a rule that would be applied at the start
and end of a word (vs string). I've tried with the \b regex symbol as
per:

  \\b A > X ;
  A\\b > Z ;

and the variant to not absorb the boundary itself:

  \\b}A > X ;
  A{\\b > Z ;

but the rules are ignored. Any help appreciated.

thanks!
