UTF-8

Postby rolliebollocks » Nov 08, 2016 1:23

Hey all. Doing some work for a client and there was a problem with a specific code being put into each document. It needs to be popped. I can do that myself.

What I need to know is whether or not a string saved from a loaded file (using print #x) will screw with the UTF-8 encoding.

If you're talking here about writing non-ASCII characters to a text file, then you shouldn't have a problem provided that:

* you specify the "utf8" encoding when opening the file
* you print a wstring to the file

For example, the following works fine on my machine:

Code: Select all

dim w as wstring*8 =  "€123.45"
open "output2.txt" for output encoding "utf8" as #1
print #1, w
close #1

If you're not using a wstring but an ascii string, then you might still be able to get way with it if the unicode characters you want to print have code points of less than 256. In this example, by knowing that the '£' sign has a unicode value of 163 I was able to print it successfully to a utf-8 file:

Code: Select all

dim a as string = chr(163) + "123.45"
open "output2.txt" for output encoding "utf8" as #1
print #1, a
close #1

Hope this helps.
