  1. This way you can create a file with unicode coding, but not in UTF-8 with byte order mark and so on. UTF-8 is not only unicode - see wikipedia. The only way in.
  2. Since your first code mostly works and the unicode code doesn't work, the file is not unicode. It is probably just an ASCII file with extended ASCII characters in it.

Nov 06, 2008 writing to unicode text files. If you want to write (and then read back) some Unicode text to file in a simple. In Visual basic 2010 it works lke this.

I'm writing data to text files from within Excel 2007 VBA that sometimes includes special characters. In the resulting file, which is being saved as a txt file, the special characters are being converted to ASCII characters. I have to go in and manually change the characters back and save the file as a UNICODE txt file. I'm using the Freefile and Print commands to create my files.

Does anyone know of a way to save the file as a UNICODE file from within VBA? Thanks for any help, Paul Hudgens Denver RE: Writing to UNICODE text files from Excel VBA (MIS) 28 Feb 12 14:55.

Visual Basic 6.0 Examples More Examples. Display Unicode Strings in Visual Basic 6.0 Displaying Unicode strings in VB6 is seemingly impossible, but it's not. A common problem is: 'My strings are displayed incorrectly, with question mark characters where non us-ascii characters should be displayed. What's going on???' Working with VB6 can be maddening when it comes to working with Unicode strings and displaying characters in different languages. The first step to enlightenment (and an end to hair-pulling) is to understand three things:. Internally, VB6 stores strings as Unicode.

When displaying a string, the standard VB6 textbox and label controls do an implicit (and internal) conversion from Unicode to ANSI. The standard VB6 textbox and label controls display the ANSI bytes according to a character encoding that you can specify.

I'll explain each point in more detail: First, make sure you understand what 'ANSI' means. ANSI is not an actual charset name. It's simply a way of saying: 'Use the default charset for this computer'.

If your program is running on a computer in France, ANSI is probably 'windows-1252', as is the case for other Western European countries, USA, Australia, etc. If you're working on a computer in Japan, ANSI is probably 'ShiftJIS'. For the Czech Republic: 'windows-1250'.

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., and there shouldn't be a problem. Problems arise only when trying to display (i.e. Render the glyphs) for foreign characters in the standard VB6 controls. When displaying a string, the standard VB6 textbox and label controls do an implicit (and internal) conversion from Unicode to ANSI.

This is the confounding behavior that causes all the trouble. Internal to VB6, the runtime is converting Unicode to the current Windows ANSI code page identifier for the operating system. There is no way to change this conversion short of changing the ANSI code page for the system. The standard VB6 textbox and label controls display the ANSI bytes according to a character encoding that you can specify.

After the Unicode-to-ANSI conversion, VB6 then attempts to display the character data according to the control's Font.Charset property, which if left unchanged is equal to the ANSI charset. Changing the control's Font.Charset changes the way VB6 interprets the 'ANSI' bytes. In other words, you're telling VB6 to treat the bytes as some other character encoding instead of 'ANSI'. 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. Given the above explanation, it is easy to see how VB6 works fine when displaying Japanese on Japanese computers, displaying Hebrew on Hebrew computers, etc. In those cases, the internal Unicode-to-ANSI conversion doesn't ruin the text rendering process that follows. The problems arise when trying to display Japanese on an USA computer, or Hebrew on a Greek computer, etc. As an example, consider trying to display a Unicode Japanese string on an English computer: You set the Font.Charset = 128 (for Japanese), but your Unicode string displays as all question mark characters.

It's because VB6 is first tyring to convert your Japanese Unicode string to ANSI, which is Windows-1252 for English computers. Japanese characters are not representable in Windows-1252. Each character fails to convert and is replaced with a question mark. So how do you do it? How can you do it so that your Japanese string displays correctly on any computer in any country? It's possible and I'll show you how.

But first, let me demonstrate that what I've said so far is correct. Consider this simple example, which can be downloaded at: Dim s1 As String s1 = 'ƒp' ' In the VB6 IDE, the Font for the Text1 textbox is set to ' MS UI Gothic w/ the Japanese script selected. ' (Selecting the Japanese script in the TextBox's property ' settings is the same as setting the Font.Charset at runtime.) ' It displays a single Japanese character: パ Text1.Text = s1 ' The Font for Text2 is set to Arial w/ the ' Western script selected. ' It displays the two characters as you see them ' in the literal string above: ƒp Text2.Text = s1 How could it be that 'ƒp' displays a single Japanese character?

Which Japanese character is displayed and why? Let's look at 'ƒp' in Unicode. After all, that's how VB stores strings internally in memory. 'ƒ' is the LATIN SMALL LETTER F WITH HOOK. Its 2-byte Unicode value is 0x0192. House of the dead. 'p' is the 'LATIN SMALL LETTER P' and it's Unicode value is 0x0070. The first thing a standard VB6 control will do when displaying a string is convert the Unicode to ANSI - and you have no control over this.

Unicode

In this case, on Western European and USA computers, 0x0192 0x0070 is converted to 0x83 0x70. (You can refer to the Windows-1252 code page here: Look for the character at 0x83 and you'll see our 'ƒ' and that the Unicode value is 0x0192.) So. The bytes VB6 will display are: 0x83 0x70.

The textbox control displays them according to its Font.Charset. Text2's Font.Charset hasn't been changed, and since we're on a computer in the USA it renders just as we expect. (Note: make sure the Font you select is capable of rendering glyphs.

As an example, 'MS Sans Serif' font does not render 'ƒ', so you'll see a thin solid rectangular box in its place.) The Text1 textbox is more interesting. Its Font.Charset has effectively been set to 128 (Japanese ShiftJIS) by setting the script to Japanese in the font properties dialog. This means that VB6 will interpret 0x83 0x70 according to ShiftJIS. If we examine the characters for that code page at you will find this: 8370 = U+30D1: KATAKANA LETTER PA You would expect this single Japanese character to be displayed, and that's exactly what happens.
