Umlaute with "Compare files"

[Matthias Wolff]

Hello,

I have two files:

contents 1: xüüx
contents 2: xüx

ü = hex code 81

When I compare these files with TC 7.00 RC 1 (Windows Vista) or TC 6.56 with compare files I get the result

left side: xx
right side: xx

where the first x ist black and the second one red.

Best regards
Matthias Wolff

OS: WinXP Prof. SP1, ger.
TC: T.C. 7.0rc1 + T.C. 6.56

Files:
uml1:

Code: Select all

xüüx

uml1:

Code: Select all

xüx

Compare result of T.C. internal compare tool:

uml1: 1:xüüx
uml2: 1:xüx

Which seems correct to me.

I get the same results as karlchen (Win XP SP2)

ü = hex code 81

That was back in the days of DOS ASCII coding that ü = hex 81 IIRC.

In Windows ü = hex FC = "Latin Small Letter U With Diaeresis"

As petermad mentioned it, DOS ü = 0x81, Ansi ü = 0xfc, I made extra sure I did use the right DOS code 0x81 (129 dec). I did.

So inside the T.C. compare window you will see a little square instead of th "ü", unless ..

Maybe the issue occurring with T.C. compare on Vista is related to the issue reported here and Christian's assumption: National chars in Vista and TC??

Unless you use a font like "Terminal" - then you will see ü's

Hi Peter !

• You are right, such a situation needs to use a complete ANSI font !

• I performed a similar test successfully, I use “Dina”, a complete fixed font which is pretty convenient
(a font I got from an our_missing_Dear_icfu-friend's info… )

This has nothing to do with Umlauts, you get the same with xaax and xax contents. Why? TC looks for insertions and deletions in strings. Single characters are ignored when re-synching, so the final 'x' is NOT matched. This is necessary to find entire word matches, and not single characters in inserted words.
