I believe make works already pretty well with UTF-8 as it is. The only thing you really need to think about is whether make depends anywhere on the assumption that 1 byte = 1 character = 1 terminal cell position because both of these equalities are true for ASCII and ISO 8859-1, but not for UTF-8. Is make using anywhere strlen() to estimate how long a string will be on the output terminal? I don't think it does any form of column formatting, or the like. Does make have any form of regular-expression matching or globbing, where a sing '.' or '?' is meant to refer to a single character, not a single byte? In that case, these matching algorithms may have to become slightly locale dependent. Does make convert anywhere between uppercase and lowercase characters or make decisions based on some classification of characters? Other than that, there is usually no need to support UTF-8 properly. See http://www.cl.cam.ac.uk/~mgk25/unicode.html and under Linux also "man utf-8" for some introductory information on the subject. > The idea I had involves changing escaped special characters like spaces > into "impossible" byte values in make's internal string representation. > That way all of make's current manipulation would continue to work > as-is: when searching for whitespace to break up words for example it > would not see the "impossible" byte values as whitespace, so it wouldn't > break on that character. > > Then, at the very last minute before make invokes a commandline, etc. it > would un-translate the string and replace the impossible bytes with the > special characters again. > > Of course, there are many details to work out, such as the user > interface for escaping special characters, exactly when the translation > back is done, etc. That sounds at first glance quite feasible to be (but then, I'm not really familiar with make's internals).
