#4 UTF-8 characters

[Marcos Cruz]

I'm trying bwBASIC 3.20 and I'm really impressed by the improvements since version 2.60, the last one I had tried.

I run bwBASIC in a GNU screen session, in a XFCE4's Terminal, on the Ratpoison window manager, on the Raspian OS (a variant of Debian compiled for the Raspberry Pi)... Everything works with UTF-8 encoding.

I can type any non-ASCII character I need in the bwBASIC command line, for example to set a string variable, but when the variable is printed the non-ASCII characteres are shown as spaces:

a$="N tilde=<Ñ>"
print a$
N tilde=<  >
rem Two spaces instead of the 2-byte UTF-8 character!

Is there any way to make bwBASIC print UTF-8 multibyte characters as expected, since the system is so configured, even if, of course, the interpreter treats them as single 1-byte characters? Or is there any by-design limitation? I have found no clue about this in the documentation.

Thank you.

Although I was the original author of bwBASIC, I have not been able to keep up with it in recent years. Is someone responding to these requests? If so, I’m grateful,

I've tried two older versions: 2.60 works fine, it prints UTF-8 characters; version 3.10 doesn't. Therefore I think this is a bug.

Marcos,

If you are comfortable editing the source code, then please try updating the function named "bwb_chartype" in the file named "bwb_int.c" to add the following. Does this resolve the issue for you?

static int
bwb_chartype (int C)
{
... not shown ...

if( C > 127 )
{
return CHAR_IS_PRINT;
}

return CHAR_IS_CNTRL;
}

[Marcos Cruz]

Perfect! I edited the code, recompiled it and now it works as expected.

I use X11-Basic and PC-BASIC for certain projects of mine that need UTF-8, but after trying bwBASIC 3.20 I'm considering it as an alternative.

I hope the UTF-8 support will be fixed in the next version of bwBASIC.

Thank you.

UTF-8 will be supported in the next release of Bywater BASIC.
