Specifies that Visual Basic should marshal all strings to Unicode values regardless of the name of the external procedure being declared. When you call a procedure defined outside your project, the Visual Basic compiler does not have access to the information it must have in order to call the procedure correctly. This information includes where the procedure is located, how it is identified, its calling sequence and return type, and the string character set it uses.
The Declare Statement creates a reference to an external procedure and supplies this necessary information. The charsetmodifier part in the Declare statement supplies the character set information to marshal strings during a call to the external procedure. It also affects how Visual Basic searches the external file for the external procedure name. The Unicode modifier specifies that Visual Basic should marshal all strings to Unicode values and should look up the procedure without modifying its name during the search.

This page explains how to pass the information to a cryptographic operation that requires the string to be encoded in UTF Rule 1. Always convert VB strings to a byte array before trying to do cryptographic operations.
Furthermore, if you pass, say, a Chinese character which requires more than one byte to store in UTF, StrConv will silently fail and just output the character as a question mark '? Flook for pointing out that the original code did not accept an empty or null string and for suggesting a correction. The Excel spreadsheet utf8-tests.
It contains two Visual basic code modules UtfTests. Here's a quick test for some accented Spanish characters.

If you want my help, then make a post and PM me it's link. If I can help, trust me I will I don't get it. Also I'm confused here. But I can't seem to arrive at that value in VB.

What's going on??? The first step to enlightenment and an end to hair-pulling is to understand three things: Internally, VB6 stores strings as Unicode. The standard VB6 textbox and label controls display the ANSI bytes according to a character encoding that you can specify. ANSI is not an actual charset name. It's simply a way of saying: "Use the default charset for this computer".
For the Czech Republic: "windows". And on and on and on Internally, VB6 stores strings as Unicode. Your VB6 program is capable of manipulating strings in any language containing any character -- whether it's Chinese, Japanese, Icelandic, Arabic, etc. It's fully Unicode capable. A single string may contain characters in multiple languages.
You can save these strings to databases, files, etc. Problems arise only when trying to display i. This is the confounding behavior that causes all the trouble. There is no way to change this conversion short of changing the ANSI code page for the system.
Charset property, which if left unchanged is equal to the ANSI charset. Changing the control's Font.

Note: VB6 is capable of displaying characters in all the major languages. It simply needs to be told to do so, and the correct bytes need to be in place internally for it to happen.To ensure that you have the latest content of this tutorial, please press Ctrl-F5 in your browser to refresh the cache.

The level of difficulty of these solutions vary but in general require intimate knowledge of ActiveX Controls and Classes. Subclassing and API programming are a must to gain functionality that Vb does not directly support.
The amount of information gathered during development of Unicode aware controls was so overwhelming that it made sense to organize it and this Tutorial proved to be an ideal place to bring eveything together under one roof.

Exe which will allow you to browse and select Unicode characters. DBCS is actually not the correct terminology for what Windows uses. It is actually MBCS where a character can be 1 or 2 bytes. To illustrate this consider the following code which will take a Unicode string of English and Chinese characters, convert to a byte array of MBCS Chinese, dump the byte array to the immediate window, and finally convert it back to a Unicode string to display in a Unicode aware textbox.
If we are setting Chinese char into the field of recordset then getting Multiple-step operation error because of the holding field size is not enough. I need some help with out changing from control panel how can we solve this problem.
