As the image below shows, WhatsApp (Web) now supports all of the active scripts in the Unicode BMP - incredible! I believe all of those fonts are in the app itself - it's not relying on system fonts at all.
The penultimate line shows a phrase in the Musa alphabet, which is encoded in the Unicode Private Use Area at E000-E1FF. As you can see, some of the codepoints are tofu, while others have emoji.
My question: is there any clever way to teach WhatsApp to use an installed Musa font to display those codepoints? Or Telegram? Or Signal?

How can we add verified tick mark on social media platforms using only Unicode? Is there a character which has a very high resemblance to it?

Yes, ☑️ or ✅ looks like those. Twitter even has a list of emojis that look like the verified symbol (and prevents those emojis from being used in usernames).
I need to change the speech language for a specific response. I know I can change the TTS voice for the whole app, but I have not found a way to do that for a response. In this case, the supported user locales are English and German, but the text I want Google Assistant to speak is in Korean.
Interestingly, there is no problem if the user locale is German and the text is in English. However, when I tried to create a response with Korean text, there was no audio feedback.
Unfortunately, the Actions on Google platform does not have support for in-dialog language changes. The case you've outlined may be an exception based on certain languages having support for other-language words which are supported as a subset in the primary language.
One alternative you might consider here is using recorded spoken audio through SSML. This is a popular way to insert custom audio output into your app, which may make sense for your use case.
I am going to design an App for iPhone 4s where user will have Speech to text feature.
When user taps on UITextView, keyboard will open with microphone option on the left of SpaceKey.
Now my question is, Can I use that microphone option as text input for textview using speech.
I dont have iPhone 4s yet, that why, I can not test it own.
As far as I know, there is no SIRI API available to developers yet (though there are quite a few asking for it).
Speech to text (i.e. the microphone next to the space bar) is a system-level keyboard feature. Any text field that uses the standard keyboard can use speech to text.
You may use the OpenEars for such purpose.
OpenEars is an open-source iOS library for implementing round-trip English language speech recognition and text-to-speech on the iPhone and iPad.
take a look of this link.
Has good discussion regarding this topic
I want to develop an iPhone application that is going to convert some sort of images to text formats. I want to know that is there any built-in library for achieving this purpose?
I suppose you are asking about recognizing text from images (OCR) and not about something like encoding image file into base64
There's no build-in OCR libraries in iPhone.
Depending on your budget and what accuracy you trying to achieve, you can try
Commertical OCR - MSDK from ABBYY http://abbyy.com/mobileocr/iphone - high accuracy, customer support, etc. but costs money. Disclaimer: I work for ABBYY
Open Source OCR - Tesseract http://code.google.com/p/tesseract-ocr/ - completely free, but less accurate. This sample shows how to run it on iPhone: https://github.com/nolanbrown/Tesseract-iPhone-Demo
I have used tesseract. Its accuracy ranges from 0-100% depending upon various factors like how well the image is captured,fonts and color of the text etc.
But it can give you very good result if you have a very clear image with very clear text.
I'm looking to commission an icon for an iphone app, and would like to provide the designers with the technical requirements. Also, as this may also be used as a logo for the website I'd like to be have a format that I can reuse and scale myself.
What technical requirements should I give to the designer and does apple have a publically linkable description of these? Is it simply 57x57 and 150x150 png or is there more to it?
Also, what is a reasonable, preferably open, scalable master format to request? I don't have photoshop and don't want to get it just for this.
The iPhone Human Interface Guidelines document about custom icons and images explains it in detail
My icon designers typically provide me with a vector file format version of my icon (usually an Illustrator file), a 512x512px TIFF file (which is submitted to Apple for use in the AppStore), and a 57x57px PNG (which is used as the actual application icon).
Also, If you want to get rid of the pre-rendered glossy bit you'll see on most iPhone apps' icons, go search for UIPrerenderedIcon, which is a flag you can set in your app's Info.plist file.
You don't need to go get Photoshop or Illustrator just for this, but you should have a 'master' file that you can keep in perpetuity in case you ever need another graphics designer to make modifications to the original icon.
