The real reason (and what may be the root cause of the LaTeX usage) is that many pre-unicode unix fonts (both for the console and X), and two common Adobe Postscript encoding vectors, had typographic opening/closing quote glyphs at these positions, so 'this' would look like ’this’, and ``this'' looked like ‘‘this’’ or ‛‛this’’, which was (especially in a ...

One reason is probably the influence of TEX to the Linux world. In most flavors of TEX, the sequence `` creates a typographically correct opening double quote (“) and '' (two single quotes) or " create a typographically correct closing quote (”). So When you type ``Why do you always say `shut up' to me?'' It actually yields “Why do you always say ...

Alt+[unicode in decimal using numpad digits] works at the console, providing your environment is properly configured to expect UTF-8 (via LOCALE or LANG environment variables). In your case, you should enter Alt + 201.

You need to escape special characters. So place a \ in front of the @ like so: export http_proxy=http://deepak:Deepak\@123@12.1.1.1:3128 Alernatively you can also use %40.

You prepend the file name with ./ (or another relative or absolute path that works). This way it's portable. Example: for zefile in ./*.tmp do rm -f "$zefile" done The use of -- to indicate the end of options is not always available. Some commands will know it, some won't. And this will change across different systems. So in the end, it's less ...

Please note that the Unicode character range is immense; There is no one font that covers all of it (although GNU FreeFont comes pretty close). If you see empty spaces, or even empty pages, it may be because they just haven't been assigned yet. Those will remain empty until the Unicode Standard utilises them. Even though there is space for 1,114,111 ...

Just press Alt R+4 like in below image: See also this answer. Note: You need to change your keyboard setting to English (India, with rupee sign) as default for this to work.

In the original name “Documents/trettiårsfirarätare”, the letter “å” is internally represented as U+00E5 LATIN SMALL LETTER A WITH RING ABOVE. This is the common representation of this character. In the filename you got back, it has been turned to the character pair U+0061 LATIN SMALL LETTER A U+030A COMBINING RING ABOVE. This is permissible, but not common; ...

Use the keyboard layout called English (international with Alt Gr dead keys). (Do this by going to System Settings > Keyboard > Layout settings, and then add the layout you want with the + button on the bottom.) This way, the keys to input the characters ', ", `, ~, and ^ become "dead keys" while you hold pressed Alt Gr. After releasing the key combination ...

I just found out how to delete such files witch special characters: cd <directory with that file> ls -ali At the very left of the directory listing you see the ID of the inode of each file. Delete your file via inode ID: find . -inum <inode ID of your file> -exec rm -i {} \; This worked fine for my issue. Hope this helps!

Keyboard layouts in Ubuntu are stored in /usr/share/X11/xkb/symbols/. The easiest way to get your desired result is to create a new layout by copying an existing one. Choose the one you are using at moment (you can have a look inside the files to find see the user friendly name of a layout). So for English (US) type sudo cp /usr/share/X11/xkb/symbols/us ...

You need the unicode hex values for these as they aren't part of the standard Compose Key lineup. To work out what the keys were, I copied and pasted the characters off your question and stuck them in this converter. There are many others like it. It gave me the following: U+25A1 : WHITE SQUARE U+25A0 : BLACK SQUARE To enter these, you follow the standard ...

I think the programs you're using all use the readline library to read input. So I guess you've misconfigured the readline library. The system configuration file is /etc/inputrc and the per-user file is ~/.inputrc. You probably put one backslash too much in a binding, so that instead of binding a command to an escape sequence you've bound it to a sequence ...

I'm afraid not. U+F200 is in the Private Use Area. These are not official Unicode characters.

The default way to do this is given in the Ubuntu Help page: The Gtk Dead Key Compose Table. The sequence for the middle dot is: ThirdLevel Chooser + DeadKey-Cirucmflex + period or expanded: AltGr + Shift + AltGr + Shift + ^ + .. This is supposed to work even without changing keyboard options. Compose key combinations, however, did not work reliably on my ...

Simply press Ctrl+Shift+U, then type "00b7Enter", i.e. the unicode value of interpunct character.

The other way is to use the following combination on any keyboard ctrl+shift+u+20b9 -> spacebar This will add the rupee symbol

I think what you are looking for is in the Unicode composition section of the Ubuntu documentation for the ComposeKey. The next bit is based on the instructions in that section. Another means to enter non-keycap characters is to enter them as a Unicode character number. Press ShiftCtrl+U. Release U while continuing to hold down ShiftCtrl. Enter the ...

This probably has to do with "Dead keys". Go to Menu>System>Preferences>Keyboard click the tab labeled "layout" and try to add a different keybord layout (I have no clue if this helps for a Romanian keybord layout). Alternatively, try to press space afterwards (instead of pressing the key twice).

Fold open "Select more options", select "Name matches regular expression" and press the Add button. Now you can fill in a regular expression to match. To use the example of Joris, put [èö] in the text box next to the "Name matches regular expression" search option you added, and it will search for all files that contain è and/or ö. You can add as many ...
