vb.net - how to correct incoming data that contains char not in Ascii to unicode before saving to the database -


i have webservice api in vb.net accepts string. cannot control data coming api. receive chars in between words in format (–, Á, •ï€,ââ€ï€, etc. ) there way me handle these or convert these characters correct symbols before saving database?

i know best solution go after source characters malformed.. i'll make plan b

my code using utf-8 encoding pattern, if client uses api messed , inadvertently sent malformed char thru api. can clean string , convert malformed char correct symbol?

if want accept ascii characters, remove non-ascii characters encoding , decoding string - default ascii encoding uses "?" substitute unrecognized characters, want override that:

' using system.text  dim input string = "âh€eÁlâl€o¢wïo€râlâd€ï€" dim ascii encoding = encoding.getencoding(     "us-ascii",     new encoderreplacementfallback(" "),     new decoderreplacementfallback(" ") ) dim bytes() byte = ascii.getbytes(input) dim output string = ascii.getstring(bytes)

output:

 h e l l o w o r l d

the replacement given en/decoderreplacementfallback can empty if want drop non-ascii characters.

you use different encoding ascii if want accept more characters - imagine of characters listed valid in european character sets.
