@kleyow Is there a ticket related to this PR? I think we need to be careful here - there was some discussion about the regex being defined in the API and we've run into problems in the past with different regex engines in the past.

@elnyry-sam-k thoughts?

Thanks @lewisdaly for catching this, appreciate it!

This came out of a fix we recently made in ALS and other places where names are used; there was support for myanmar script missing in the current regex; I discussed this with Kevin following the fix we made here: mojaloop/project#2358. Miguel corrected the regex to use the correct implementation interpretation of \w now which actually implements the regex as intended in the original FSPIOP Spec

mojaloop/project#2358

We know the \w in Javascript land does not match the intended Mojaloop Interface Specification. API Snippets should be modified to implement a regex pattern that matches the intended Unicode groups.

@lewisdaly see the following comment: mojaloop/project#2358 (comment) specifically.

That describes how we came to this regex pattern, and as per @elnyry-sam-k's comment...I believe it is as close as one can get to the standard Unicode definition for \w, unless Javascript ECMAScript actually implements the latest Unicode standards for \w.

Here is some additional "historical" context around this, and how the original regex alternative pattern came about: mojaloop/project#1261.

This PR is +1 from me, but I would prefer to wait for @lewisdaly to confirm that he is happy with this change. @lewisdaly please confirm from your side.
