language - Specific characters displaying as boxes in Windows 7


I'm currently experiencing issues with "exotic" unicode characters that are displayed as boxes (for example, Bananas ).


I've searched a bit how to extend Windows character set, but didn't find anything working yet. I've tried to play with language packs, but when trying this, I simply don't see these updates in the Optional tab, nor do I see, in Regions and Languages > Keyboard and Languages, a box under Keyboard and other input languages with the title Display language.


I then would like to know how can I extend the character set supported by Windows.


Is that even a matter of language, or a matter of font ?



Answer



There is really no “Windows character set” to extend. Characters like BANANA (U+1F34C) are recognized and processed, they just aren’t displayed, because no font in the system contains it or, depending on program and context, the font(s) being used by the rendering software do(es) not contain it.


So it’s a font issue. Some language packs may contain additional fonts (though I doubt that), but BANANA isn’t language-specific but an icon-like character. The page that you link to has a link to Fonts that support U+1F34C. Such links at Fileformat.Info are often very useful, but for very new characters like this, there might be some information missing. In this case, the page mentions just the free font Symbola (LastResort isn’t a real font), but in reality, sufficiently new versions of Segoe UI Symbol have BANANA, too.


Segoe UI Symbol is shipped with Windows 7, but the version you have might not be the newest one, so check for the update available from Microsoft.


For different exotic characters, you may need different exotic fonts.


Note that characters with Unicode numbers larger than FFFF (such as BANANA, which has 1F34C) are outside the “16-bit subspace” of Unicode, called Basic Multilingual Plane (BMP) and often cause problems in software that is not capable of handling it, or require special measures.

Use Google instead of Bing with Windows 10 search

I want to use Google Chrome and Google search instead of Bing when I search in Windows 10. Google Chrome is launched when I click on web, but it's Bing search. (My default search engine on Google and Edge is http://www.google.com ) I haven't found how to configure that. Someone can help me ? Answer There is no way to change the default in Cortana itself but you can redirect it in Chrome. You said that it opens the results in the Chrome browser but it used Bing search right? There's a Chrome extension now that will redirect Bing to Google, DuckDuckGo, or Yahoo , whichever you prefer. More information on that in the second link.

linux - Using an index to make grep faster?

I find myself grepping the same codebase over and over. While it works great, each command takes about 10 seconds, so I am thinking about ways to make it faster. So can grep use some sort of index? I understand an index probably won't help for complicated regexps, but I use mostly very simple patters. Does an indexer exist for this case? EDIT: I know about ctags and the like, but I would like to do full-text search. Answer what about cscope , does this match your shoes? Allows searching code for: all references to a symbol global definitions functions called by a function functions calling a function text string regular expression pattern a file files including a file

How do I transmit a single hexadecimal value serial data in PuTTY using an Alt code?

I am trying to sent a specific hexadecimal value across a serial COM port using PuTTY. Specifically, I want to send the hex codes 9C, B6, FC, and 8B. I have looked up the Alt codes for these and they are 156, 182, 252, and 139 respectively. However, whenever I input the Alt codes, a preceding hex value of C2 is sent before 9C, B6, and 8B so the values that are sent are C2 9C, C2 B6, and C2 8B. The value for FC is changed to C3 FC. Why are these values being placed before the hex value and why is FC being changed altogether? To me, it seems like there is a problem internally converting the Alt code to hex. Is there a way to directly input hex values without using Alt codes in PuTTY? Answer What you're seeing is just ordinary text character set conversion. As far as PuTTY is concerned, you are typing (and reading) text , not raw binary data, therefore it has to convert the text to bytes in whatever configured character set before sending it over the wire. In other words, when y...
