However, for Chinese-Japanese-Korean (CJK) scripts, UTF-8 can require three bytes for each character, and can potentially cause larger data sizes than UTF-16. Format(" ", Chr W(&h24C8), Chr W(&h2075), Chr W(&h221E)) Console.
Note that sometimes the amount of ASCII data, such as HTML tags, justifies the increased size for the CJK range. NET includes the Encoder Replacement Fallback and Decoder Replacement Fallback classes, which substitute a replacement string if a character does not map exactly in an encoding or decoding operation.
For sequences that include non-ASCII characters, UTF-7 requires more space than UTF-8, and encoding/decoding is slower. To throw an exception in encoding and decoding operations, you supply an Encoder Exception Fallback object and a Decoder Exception Fallback object, respectively, to the Encoding. Write Line() ' Encode the original string using the ASCII encoder. If count = 1 Then Return False ' Determine number of characters to return. count -= 1 ' If count is less than zero, we've returned all characters.
Consequently, you should use UTF-8 instead of UTF-7 if possible. Get Encoding(String, Encoder Fallback, Decoder Fallback) method. If count object and passes an instance of it to the Encoding. Generic Module Module1 Sub Main() Dim enc As Encoding = Encoding.
The last 128 code points in code page 1253 contain the Greek characters.
