Re-iterating the question on SO <https://stackoverflow.com/questions/20937864/> of applying an accent-insensitive grep to text. (e.g: all accents of a letter 'e' should be regarded as an ascii 'e').
The response by Adam Katz mentions:
You should not expect equivalence classes to be portable as they are too arcane.
What's the stance of grep developers on this? are equivalence classes the right tool to approach this? I see that they depend on LC_COLLATE, in which case it would be possible to setup a custom locale that matches digraphs. In the example he gave, he also mentions:
This matches all words like aei... [but won't match] æi... it's quite likely that digraphs are beyond the reach of even the best equivalence class map.
Is there a way to setup a locale without having to recompile glibc or are these locale values hardcoded into programs using glibc? Thanks, Avid
