[Rlib-devel] Locale problem in RLIB

[Zoltan B. <zb...@du...>]

Hi Bob,

Hungarian problems again. :-)

Now I reached a phase where my program actually compiles and works
under Windows, and links to RLIB. But the resulting PDF is unusable.
Of course I saved it in an O_BINARY file. The problem is that printf(),
et.al. are conforming to the locale settings, so controlling numbers
in the PDFs are written as e.g.

/Frpdf0 9,000 Tf

instead of

/Frpdf0 9.000 Tf

since the decimal separator is a comma, not a dot here in Hungary.

A simple trick will do it (I fixed unixODBC this way in 2000):

-------------------------------------------
char *saved_locale;

saved_locale =3D strdup(setlocale(LC_ALL, NULL));

/* national decimal separator here */
setlocale(LC_ALL, "C");
/* decimal dots strictly required here */
setlocale(LC_ALL, saved_locale);
/* national decimal separator again */
free(saved_locale);
-------------------------------------------

Fortunately setlocale() exists under MingW, too.

I haven't made a patch against RPDF yet, but you know better
where to fix it.

Best regards,
