How to use "Compare by contents" highlight effect?

[sky66]

I found the picture on TC website, but I don't know how to shown different words highlight effect as below?
http://www.ghisler.com/screenshots/en/07.html

For example this is what I want:
Left: write_header($lang);
Right: write_header($lang_id);

Actual in TC 8.x, it will be hard to find out the difference.
Left: write_header($lang);
Right: write_header($lang_id);

I made two files with mentioned strings, and TC 8.50 compare tool displayed differences as you want.

TC 8.51 b3 displays it just the way you want.

What ?!
I had used this function for long time, and I always get the wrong results due to Notepad default is ANSI.

After test,
1. If Notepad save two files encoding as ANSI,
TC will compare them with ANSI => No good

2. If Notepad save two files encoding as Unicode,
TC will compare them with Unicode (UTF-16) => OK

3. If Notepad save two files encoding as Unicode big endian,
TC will compare them with Unicode MacOS => OK

4. If Notepad save two files encoding as UTF-8,
TC will compare them with UTF-8 => OK

Is this a problem bug? Because I also test the other tool, it can compare them with ANSI and get the correct results.

I tested it with two ANSI files, and all was OK.
And I don't use Notepad, I use comfortable text editor.

Maybe you should upload archive with test files so we would reproduce your behaviour.

[Horst.Epp]

I tested with ANSI files, result is ok.
As MVV alrady said use one of the many free editors available
all of them are better than Notepad.

Notepad is not good enough, but it is my old friend, since 199?

ANSI & UNICODE files as following, write by Notepad, and encode by TC.

Both pairs of files compare fine here

[MVV]

For me too.

BTW it would be much more convenient to encode one zip archive with all four files (it is irritating to decode 4 files instead of just one).

[petermad]

Here the ansi files 1-1.txt and 1-2.txt provided by sky66 compares like this:

Left (1-1.txt): write_header($lang_id);
Right (1-2.txt): write_header($lang);


which is the same as the unicode files - so I cannot confirm the bug.

After test with different computer & OS. (Update results)

1. English Windows XP + TC 8.5(ENG) compare with ANSI => OK
2. English Windows XP + WCMD 4.0(ENG) compare with default => OK
3. English Windows XP and change "non-Unicode programs" in Control Panel(Regional and Language options) to "Chinese(TW)"+ TC 8.5(ENG) compare with ANSI => NG

4. Chinese Windows XP + TC 8.5(ENG) compare with ANSI => NG
5. Chinese Windows XP + WCMD 4.0(ENG) compare with default => NG
6. Chinese Windows XP and change "non-Unicode programs" in Control Panel to "English(US)"+ TC 8.5(ENG) compare with ANSI => OK

7. Chinese Windows 7 + TC 8.5(ENG) compare with ANSI => NG
8. Chinese Windows 7 + WCMD 4.0(ENG) compare with default => NG
9. Chinese Windows 7 and change "non-Unicode programs" in Control Panel to "English(US)" + TC 8.5(ENG) compare with ANSI => OK

3. English Windows XP and change "non-Unicode programs" in Control Panel(Regional and Language options) to "Chinese(TW)"+ TC 8.5(ENG) compare with ANSI => NG

I can confirm this with Danish Windows XP and "Kinesisk "Taiwan" set up for non-unicode programs.

The test file compare like this:

Left (1-1.txt): write_header($lang_id);
Right (1-2.txt): write_header($lang);

I also tried to add a second line to the files to see if it was only present in one line files, but it still compares both lines wrongly.

Apparantly an old bug - testet it with TC 6.54, 7.04 and 8.01 - and they all have it.

It's not a bug, TC just doesn't support by character selection in multi-byte languages.
