I see. Thanks.

FYI (mostly off topic), I think the hyphen-minus is considered both an ASCII char as well as Unicode.

######### START MOSTLY OFF TOPIC REFERENCE #########

Reference:

Quote:
The hyphen-minus (-) is a character used in digital documents and computing to represent a hyphen () or a minus sign (').

It is present in Unicode as code point U+002D - HYPHEN-MINUS; it is also in ASCII with the same value.
Where is the hyphen in duckduckgo.com ?

My understanding is that hyphens used in domain names are generally coded in ASCII, FYI.

Reference:

Quote:
The characters allowed in a domain name include letters (abc), numbers (123), and dashes/hyphens (---). No spaces are allowed and the domain name can't begin or end with dash/hyphen.
In the case above (in a permitted domain name char), the hyphen is considered ASCII.

Anyway, this is not germane to your question, which is related to GTK applications.

######### END MOSTLY OFF TOPIC REFERENCE #########

My best guess is that your GTK application has an input filter which checks for non-ASCII chars and pops up an error message when non-ASCII is detected.

The way around this, off the top of my head, is of course to look at the source code, verify the code which is detecting the non-ASCII char (and giving the error pop up) and then comment that code out and recompile and test it.

Here is a link to the source:

Hope this helps a little bit.

NAME
cvtenc - file encoding converter SYNOPSIS
cvtenc [-Encoding encoding] [-EscapeIn yes|NO] [-EscapeOut yes|NO] filename DESCRIPTION
Converts a file encoded in a specified or default non-unicode encoding to unicode (UTF16), or, if the file is already in unicode, converts it to a specified or default non-unicode encoding. The converted text is printed to standard out. If the filename is a hyphen then this tool reads from standard input. OPTIONS
-Encoding encoding Specify non-unicode encoding to be used. The direction of conversion depends on whether the file given as input is recognized as uni- code (from the higher order bytes). To get a list of available encodings, enter "list" for the encoding. If this is not specified, the default encoding for the current locale is used. -EscapeIn YES|NO Specify '-EscapeIn YES' (the default is 'NO') to parse the input for u escape sequences (as in property lists). -EscapeOut YES|NO Specify '-EscapeOut YES' (the default is 'NO') to generate u escape sequences (as in property lists) in the output. Note, this might produce unexpected results for some encodings. -Unicode IN|OUT Specify '-Unicode IN' (or '-Unicode OUT') to control the direction of conversion rather than having the tool guess it on the basis of the content it reads. Using '-Unicode IN' means that the tool reads UTF16 data and writes C-String data, while using '-Unicode OUT' merans that the tool reads C-String data and writes UTF16 data. HISTORY
