Haxe error: "invalid escape sequence"

[Daniel Glazman]

I would like to come back to an old message [1] posted here, back in
2007:

>> Haxe compiler 1.10 throws "invalid escape sequence" at the following

If I understand the rationale for \b, I think the decision
above should be reverted for \f for \v. \f is ubiquitous when you start
writing a parser of some arbitrary language, whether your parser
is based on regexps or not. \v is super-common too.

Personally, I haven't heard about these escape sequences (let alone
used those characters) until now, so with the data available to me I
favor of the current decision. Maybe you could point us to some
examples (on github or whatever) that put these escape sequences to
good use.
