I have an html file that I need to replace some characters with html entities. Right now I'm trying to replace — with — but when I use the Replace All button, the result is that all of those instances of — are replaced with —mdash;
I thought maybe escaping the "&" will work, so I changed the Replace with value to \— but that just results in \—mdash;
The strange thing is that if I go to each, one by one, i.e., click Next, then click Replace, and so on, then it replaces it correctly.
Is this a bug in MacVim? Or am I missing something?
Enter into command line:
:%s/—/\—/g
Also it's possible to get character code. Place your cursor on the character and press ga. Use decimal, hex or octal code into replacement string:
\%d match specified decimal character
\%x match specified hex character
\%o match specified octal character
\%u match specified multibyte character
\%U match specified large multibyte character
:%s/\%d8212/\$mdash;/g

I’m printing a parameter returned from a query that’s a string of letters and underscores.
The label prints just the letters without the underscores, and I’m not sure how to fix it.
^FD<String>^FS
^FH^FD<String>^FS
Thank you very much.
(Removing the FH Only reads to the first underscore.
The ^FH command without parameter defaults to underscore as the hexidecimal escape character. Either remove the ^FH or specify a different escape character like backslash using ^FH\^FD<String>^FS.
I am new to SF. I have a typical problem that I have faced while loading some data. The delimiter is part of extended ascii. It does not come in 0-127. We use thorn (ascii - 254) as delimiter. My Qn is while specifying the delimiter can I give the ascii code of that delimiter instead of actual character (44 instead of comma, 9 instead of tab etc)
Thanks in advance
You can specify the hex/octal code of any valid Unicode delimiter in the FIELD_DELIMITER option of the File Format. From the documentation:
The specified delimiter must be a valid UTF-8 character and not a random sequence of bytes.
For example, for fields delimited by the thorn (Þ) character, specify the octal (\336) or hex (0xDE) value. Also accepts a value of NONE.
Placing an ASCII 10 (0A) character somewhere inside of a segment of an HL7 message to represent a new line character. Is this valid?
From what I can see it is recommend to use \X0D\ or \X0D0A\ to represent a new line character for plain text format HL7. Is using just the 0A ASCII character explicitly invalid HL7?
To respond to the question "Is using just the 0A ASCII character explicitly invalid HL7?":
The character 0A is not mentioned anywhere in the HL7 specs as being special.
Extract from the HL7 2.5 US specs:
2.5.4 Message delimiters
In constructing a message, certain special characters are used. They are the segment terminator, the field
separator, the component separator, subcomponent separator, repetition separator, and escape character. The
segment terminator is always a carriage return (in ASCII, a hex 0D). The other delimiters are defined in the
MSH segment, with the field delimiter in the 4th character position, and the other delimiters occurring as in
the field called Encoding Characters, which is the first field after the segment ID. The delimiter values used
in the MSH segment are the delimiter values used throughout the entire message. In the absence of other
considerations, HL7 recommends the suggested values found in Figure 2-1 delimiter values.
Strictly speaking this would mean that you could use the character 0A just as any of the characters other than the 6 previously mentioned.
<end of "formal" reply>
That being said, I concur with Dale H. that you should better stay away from using this character in the content of an HL7 message. Since most editors (except old-fashioned Notepad on Windows) will display this character as a new line, you might unwillingly think that a segment was truncated or malformed. And I've had at least one instance where the interface engine indeed handled that character as a segment termination (which in itself is invalid, and the interface engine build was modified to not do this anymore).
So better avoid this. But in situations where you don't control the output, it doesn't seem to be a formally disallowed character...
Linefeeds (0x0A) are not allowed in HL7 messages. If you edit messages with notepad, wordpad and many other text editors, they will convert carriage returns (0x0D) to CR/LF (0x0D 0x0A) and if you save, you now have a corrupt HL7 message. Avoid LFs (0x0A).
If you only send 0A then there is no way to determine that you wanted ASCII 10/line feed and it would be assumed you wanted a zero and an A.
Standard HL7 with the escape character being a \, then yes the recommended way would be \X0A\. The \X representing the start of hexadecimal data, followed by two-character hexadecimal values, ending with a \.
That being said, if you are sending this data to a system then they should be able to tell you what they accept for lines feeds. I've seen systems that use \.br\ or the repetition character ~ to determine a new line. And sometimes they want repeating segments. For example below, each OBX segment is a new line of a report in the system.
OBX|1|TX|||This is line one
OBX|2|TX|||This is line two
I have the following line in a plugin to display page views on my Jekyll site:
html = pv.to_s.reverse.gsub(/...(?=.)/,'\& ').reverse
It adds space between thousands, for example 23 678.
How can I add hair space instead of regular space in this string?
In HTML is a so-called decimal numeric character reference:
The ampersand must be followed by a "#" (U+0023) character, followed by one or more ASCII digits, representing a base-ten integer that corresponds to a Unicode code point that is allowed according to the definition below. The digits must then be followed by a ";" (U+003B) character.
Ruby has the \u escape sequence. However it expects the following characters to represent a hexadecimal (base-sixteen) integer. That's 200A. You also have to use a double-quoted string literal which means now the \ character needs to be escaped with another one:
"\\&\u200A"
Alternatively just use it directly:
'\& '
I am new to ruby and I'm trying to work with regex.
I have a text which looks something like:
HEADING
Some text which is always non capitalized. Headings are always capitalized, followed by a space or nothing more.
YOU CAN HAVE MULTIPLE WORDS IN HEADING
I'm using this regular expression to choose all headings:
^[A-Z]{2,}\s?([A-Z]{2,}\s?)*$
However, it matches all headings which does not contain chars as Č, Š, Ž(slovenian characters).
So I'm guessing [A-Z] only matches ASCII characters? How could I get utf8?
You are right in that when you define the ASCII range A-Z, the match is made literally only for those characters. This is to do with the history of characters on computers, more and more characters have been added over time, and they are not always structured in an encoding in ways that are easy to use.
You could make a larger character class that matches the slovenian characters you need, by listing them.
But there is a shortcut. Someone else has already added necessary data to the Unicode data so that you can write shorter matches for "all uppercase characters": /[[:upper:]]/. See http://ruby-doc.org//core-2.1.4/Regexp.html for more.
Altering your regular expression with just this adjustment:
^[[:upper:]]{2,}\s?([[:upper:]]{2,}\s?)*$
You may need to adjust it further, for instance it would not match the heading "I AM A HEADING" due to the match insisting each word is at least two letters long.
Without seeing all your examples, I would probably simplify the group matching and just allow spaces anywhere:
^[[:upper:]\s]+$
You can use unicode upper case letter:
\p{Lu}
Your regex:
\b\p{Lu}{2,}(?:\s*\p{Lu}{2,})\b
