That strange character — � (called the replacement character) — appears when a browser or text editor encounters bytes that don’t match the expected character encoding. It usually appears when a fraction character was used when pages were saved using the ISO-8859-1 charset, but that is obsolete with almost everything (including WC) now using UTF-8.
Any help determining what they should be in this document?
I recently purchased a General Band Saw, Model 490-1 other wise called a 15". The base model came with factory guides (re saw capacity at 6 1/8") and a � hp motor. I chose to upgrade to Carter Guides (re- saw at just over 6 �"), a 1 hp Baldor motor (factory wired for 220v on a 15 amp plug), a miter gauge and fence as well. I also purchased a mobile base for the unit, a HTC (not happy with it) that I may return to Ashmans for a Delta base. The assembly instructions are not well done and were the only disappointment. Given that the assembly was straightforward and clearly easy to complete. The hardware was all there, it is of high quality and standard size P/D on all the threads.
The saw was delivered from General 7 days from the placement of order, it came semi assembled in several large boxes. The fence was on back order so I will have to let you know about it later. The total weight of the machine is called out at 345 lbs. with a closed base housing the motor on an adjustable mounting bracket to assist in belt tensioning. The switch is also located on the base and is a standard single throw switch rated for 220v and 20 amps I believe. The base is welded sheet steel and has door to access the motor on the back.
The upper frame is a massive box type one piece of cast steel, it is well ribbed and weighs a ton. I need to get help to lift it on to the base during assembly. It has two stamped hinged doors with a 2" dust port located below the front door. The throat opening is not 15", but 14 �" and the wheels measured about 14 7/8" in diameter. The wheels are heavy cast, very good quality tyres and turn true, they were in perfect alignment from the factory and required no adjustment at all. The blade tension control operates very easily and smoothly, the scale is clear and easy to read as well. It also came with a �" 3 TPI blade of good quality, but since I had purchased some Timber Wolf Blades I replaced it soon after set up and my first confirmation cut.
The table is dead flat and dimensioned at about 15 1/2" square. It has the standard miter slot and is also made in the same cast material and is heavily ribbed. It has a 45 deg. right tilt and 10 deg. left tilt with an adjustable dead stop that was factory set at 0 deg. exactly. The table is firmly supported on dual trunnions (with dual screw locks) and the scale is clear and located on the face of the front trunnion.
After Full assembly and power up I ran the Band saw for about a half-hour and it was a pure pleasure. It runs very quiet and is steady from vibration and noise. I set up the saw and was able to re saw without a problem (a function of the blades more than anything else I would suspect) and make all the other cuts one would consider with a band saw as well. It was getting late and I needed to put it away for the night, felt real good!
I had considered other machines (Closed base Jet, Delta) in this purchase but decided to spend a little more and go for it in the end. Over all it is a pleasing machine to look at and use, everything fit where it was supposed to and the finish is very good. It's not a Laguna, but then again it fits into the niche I needed to round out my shop.
I have absolutely no idea what you're talking about "fration" (fraction ?) characters but is it a case where there are spaces where there shouldn't be spaces. When I put an extra space while typing this, the editor underlines the fore and after word. Could it be your editor is just telling you to drop the space. Addy protocol: I'm not a programmer.
In this example, most of the characters appear to be remnants from a charset that’s no longer in use. Sometimes you can make an educated guess—especially if you’re familiar with the topic and context—but after reviewing it, I don’t think it’s possible to determine the original characters with certainty.
Learning Something New Every Day
I came across a Linux command
iconv
which can read a file in one charset and convert it to another. Ideally, I’d like to automate this process to handle the millions of files on WC, since manually identifying and fixing problematic files isn’t a realistic approach.
🧠 What a Charset Is
A charset defines how a computer represents text — that is, how bytes are turned into characters. Every character you see (like A, é, ½, 你, or 🙂) has to be stored internally as numbers (bytes). A character encoding (or charset) specifies the mapping between those numbers and characters.
For example:
Character
ASCII (byte)
UTF-8 (byte)
Windows-1252 (byte)
A
65
65
65
é
—
195 169
233
€
—
226 130 172
128
Different encodings interpret those bytes differently — which is why the wrong charset produces “�” or gibberish.
🌐 Why Charsets Are Needed for Web Pages
When a browser receives a web page, it just gets a stream of bytes. Without knowing the charset, the browser has no idea how to turn those bytes into readable text. So, web pages (and servers) must specify which charset they’re using — for example:
1️⃣ In HTML
<meta charset="utf-8">
2️⃣ Or in the HTTP header
Content-Type: text/html; charset=utf-8
If this information is missing or wrong, the browser guesses — sometimes incorrectly — leading to broken symbols, question marks, or replacement characters (�).

Description
Notes
UTF-8
Universal Unicode encoding
Supports every language and symbol; the modern web standard.
ISO-8859-1 / Latin-1
Western European
Legacy from early web days.
Windows-1252
Microsoft’s extended Latin-1
Common on old PCs; adds symbols like “€” and “–”.
UTF-16 / UTF-32
Unicode encodings using 2 or 4 bytes per character
Used internally in some systems, but rare for web.
🚀 Why UTF-8 Is Standard Today
It can represent all characters (English, Chinese, Arabic, emoji, etc.).
It’s backward compatible with ASCII (so older English text still works).
It’s efficient — common characters use only 1 byte.
It avoids problems with mixed encodings.
Modern browsers, editors, and web servers default to UTF-8, and nearly all web standards recommend it.

Why it matters
Ensures text displays the same on all systems and languages
Interesting, peter - I saw the same pattern as you above. 1/8th shows, but I remember seeing the fourths in fraction characters. 1/8th probably didn't make the font or text set and survived fine because it wasn't a special character.
I don't know if you're jewish (i'm not, at least not much as far as bloodline goes), but the idea of doing those characters manually reminds me of listening to a guy who had spent 40 or 50 years manually cleaning up torah scrolls that either needed to be repaired, or worse, they needed to be fixed because they were repaired improperly.
manual repair of what's often a lot of drivel would be like hand writing the scrolls (let alone repairing them), except there's no religious reward.
I mean, unless you could find someone with a very special case of OCD where they live to fix things like that. I've worked with a few.
