#258: Search & Replace in Query Tool trips over multibyte characters

Priority: minor | Milestone:
Component: pgadmin | Version: trunk
Keywords: Query Tool | Platform: windows
------------------------+---------------------------------------------------
Testing pgAdmin v1.12.1 on Win XP Home & Pro.
(Bug exists in v1.12 and v1.10 as well.)

Searchstrings with multibyte characters (like German umlauts) are found
correctly. But byte-length and character-length get mixed up in the
highlighting of the matching text.

That's what seems to happen:
1.) Count number of _characters_ in the search-string.
2.) Highlight matching string for as many _bytes_ (instead of characters).

So If you paste a string of 2-byte characters (in utf8 encoding) and
search for it:
öööööööööö
only characters 1 to 5 get highlighted.

If you try the same with 3-byte chinese symbols:
漢族人漢族人
only the leading third of the search-string is highlighted.

As a consequence, [Replace] does not work at all with multibyte character
in the search-string. (Works with multibyte chars in the replace-string,
though.)
