tip: unichar code finder pbix
hi all:

while preparing for challenge #5, i started a small pbix to test how unicode values rendered inside power bi desktop and identify a few i might find useful. i cleaned it up a bit and added some named measures, and i thought i’d share it with you as a reference.

just adding some keywords to make this tool easier to locate via forum search: unichar, arrow, triangle, circle, stop sign
even if you get the binary contents, decoding it is quite the undertaking. you can find the format specs here if you want to try it, though:

Some kind soul scanned the code book. not [full disclosure] a linux person per se.

something similar to the following should work:

start simple with just enough code to test the concept.

see if it works and modify/correct as necessary.

then if it still does not work, then post your documented code accordingly along an explanation of what is or is not happening as you expect or desire. thanks for the info joe. as it happens i can confirm this; i was teaching on a workshop yesterday and one of the delegates was using a win10 high-res display (a retina display mac booted into win10) and we saw exactly that.

the work around we used was that pixel units seemed to work fine; text beca… its kind difficult to understand in my POV but not impossible

can you show some codes? or samples on what you want to achive? How about in c++?

Unicode can be a problem, and Perl has its own quirks. Essentially, Perl creates a firewall that surrounds all Unicode I / O capabilities. You must tell Perl if the I / O path is encoded. If so, the DECODE rule for any input and / or ENCODE for any output.


Decoding converts the data from {encoding} to Perl's internal representation, which is probably a combination of bytes and code points.


The coding is just the opposite.


Thus, it is actually possible to "decode into" and "encode" up to two different encodings. You just need to say what it is. Encoding / decoding is usually done with the file I / O layer, but you can use the encoding module (distribution part) to manually convert between encodings.

Here's an example that can help visualize it (there are many other ways).



```
use strict;
use warnings;
use Encode;


# This is an internalized string with these UTF-8 codepoints
# 
my $internal_string_1 = "\x{C7}\x{69}\x{64}\x{65}\x{6D}\x{5F}\x{15E}\x{65}\x{6E}\x{65}\x{72}\x{20}\x{48}\x{FC}\x{73}\x{6E}\x{FC}\x{20}\x{54}\x{61}\x{11F}\x{6C}\x{69}\x{70}";


# Open a temp file for writing as UTF-8.
# Output to this file will be automatically encoded from Perl internal to UTF-8 octets.
# Write the internal string.
# Check the file with a UTF-8 editor.
# 
open (my $out, '>:utf8', 'temp.txt') or die "can't open temp.txt for writing $!";
print $out $internal_string_1;
close $out;


# Open the temp file for readin as UTF-8.
# All input from this file will be automatically decoded as UTF-8 octets to Perl internal.
# Read/decode to a different internal string.
# 
open (my $in, '<:utf8', 'temp.txt') or die "can't open temp.txt for reading $!";
$/ = undef;
my $internal_string_2 = <$in>;
close $in;


# Change the binmode of STDOUT to UTF-8.
# Output to STDOUT will now be automatically encoded from Perl internal to UTF-8 octets.
# Capture STDOUT to a file then check with a UTF-8 editor.
# 
binmode STDOUT, ':utf8';
print $internal_string_2, "\n\n";


# Use encode() to convert an internal string to UTF-8 octets
# Format the UTF-8 octets to hex values
# Print to STDOUT
# 
my $octets = encode ("utf8", $internal_string_2);
print "Encoded (out) string -> UTF-8 (octets):\n";
print " length = ".length($octets)."\n";
print " octets = $octets\n";
print " HEX val = ";
for (split //, $octets) {
    printf ("0x%X ", ord($_));
}
print "\n\n";


# Use decode() to convert external UTF-8 octets to an internal string.
# Format the internal string to codepoints (hex values).
# Print to STDOUT.
# 
my $internal_string_3 = decode ("utf8", $octets);
print "Decoded (in) string <- UTF-8 (octets):\n";
print " length = ".length($internal_string_3)."\n";
print " string = $internal\_string\_3\n";
print " code points = ";
for (split //, $internal_string_3) {
    printf ("\\x{%X} ", ord($_));
}

        

        
        
        
 (adsbygoogle = window.adsbygoogle || []).push({});
 
        

    
```

What attempts have you made at this? Have you got any code written yet?
