   WebView1.LoadHtml("<p>&#xFE4E6;</p>")
 
   EditText1.Text = UnicodeToString(0xFE4E6)

Sub UnicodeToString (codepoint As Int) As String
   Dim bc As ByteConverter
   Dim b() As Byte = bc.IntsToBytes(Array As Int(codepoint))
   Return BytesToString(b, 0, 4, "UTF32")

You should copy this your code to the section "Snippets", dear new member (Erel), please.

Thank you

Thanks Erel!
This looks like it runs on KitKat very well. Can it function on ICS or JellyBean?
Rusty
I tried it on ICS and it doesn't seem to work. Does ICS support the UTF16/32?

It depends on the font. Try to use a custom font file that includes these characters.

You are right. I had loaded a custom font and then later in the test program had loaded another ...
I appreciate your help, Erel.

Rusty

In ICS, the B-) generates a Unicode character and this is working well. The edit text shows the correct smiley.
How can I get the Unicode code point value? Is there a translation table for these texts? If so, it seems they vary between Android OS's...ICS, JB, ...
The reason I need this is that I can't find a "map" that gives the code point value for the text representations (like above).

B4X:

From ICS soft keyboard smiley button
":-)"
"B-)"
":'("
":-["
":-!"
":)"
":-*"
":-D"
":-X"
":-$"
":-O"
":-P"
":-\"
";)"
"o.O"
":0"
":-|"
":("
"x-("
"<3"

Thanks,
Rusty

The editor-app for sms (or whatever you are looking at) seems to have the maps hardcoded...
I dont know whether there exist an mapping for text-smilies to graphics.

Thanks Manfred,
We have written our own and as such, we are mapping them...

Does anyone know how/where/which codepage/unicode values the Korean character set resides?
If so, can you please advise on how I might reach this in code?
Thanks,
Rusty

You don't need to do anything special.

B4X:

Activity.Title = "안녕하세요"

Thanks Erel.
I need t be able to "combine" Unicode characters such as Korean where selecting consonants and vowels result in a single combined ligature/glyph.
Does android/b4a support this function or is there a "formula" by which this can be accomplished?
for example: ㅁ plus ㅕ results in the character 며 adding another ㅁ results in 몀
Regards,
Rusty

I see. My Korean is a bit rusty.
I think that you can use the Hangul characters: http://www.ssec.wisc.edu/~tomw/java/unicode.html#x1100

Nothing wrong with being RUSTY, I've been that for my whole life
Thanks for the speedy response.
Do you know how to "Add" the consonant value to the vowel value that points to the codepage/glyph with the resultant character?
Thanks,
Rusty

I'm afraid no. Try to find a Java solution and I can help you convert it. I didn't find any.

I think there is a "Normalizer" that will do this:
http://www.programcreek.com/java-ap.../hivemall/tools/text/NormalizeUnicodeUDF.java
This might be better:
https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/normalize
Java code looks like it might do the job with the Android Normalizer.
Any help with this is appreciated.

It works.

B4X:

Dim s As String = "ㅁㅕ"
Dim jo As JavaObject
jo.InitializeStatic("java.text.Normalizer")
For Each form As String In Array("NFD", "NFC", "NFKD", "NFKC")
   Log(jo.RunMethod("normalize", Array(s, form)))
Next

form should be either NFKD or NFKC

Are there other "formats" for normalize?
Some of the combinations have multiple "pieces" i.e. "ㅁ", "ㅕ", "ㄱ" result in 멱
When I send it an array of three elements, it doesn't combine all three, just the first two and then sets the third as an independent character.
THanks
