Phonetic Fonts: Testing "Charis SIL " Font

Robert Mannell, 2012

In the following table columns 1 and 2 represent the decimal (base 10: digits=0-9) and hexadecimal (base 16: digits=0-9,A-F) value of the character in the Unicode standard. Column 3 contains a graphical image of each character as it should look except that the images are coloured grey. Also note that some combining characters, or "diacritics", are displayed with a grey dotted "o". The grey dotted "o" is included so that you can see the position of each diacritic relative to a preceding character. Column 4 contains the actual font being tested as displayed by the current browser (note that the diacritics are displayed in this column with a black solid "o").

If the font is being displayed accurately then the characters in columns 3 and 4 should look identical with the exception of the following non-significant differences:-

  • grey characters in column 3 and black characters in column 4
  • grey dotted "o" versus the black solid "o" associated with the diacritics
  • there might also be slight differences of font size and weight

Missing Characters

Some browsers display missing characters as a narrow vertical rectangle rather than as the intended character. Most often, these days, the system looks for a font with the missing character and displays that character instead. Such an inserted character may look very different in size or style from the intended font. This may very often be useful when browsing, but it makes the testing of phonetic fonts far more difficult as it can be hard to tell, sometimes, whether a character came from the expected font or some other font.

Serif and Sans Serif Fonts

image comparing sefif and sans serif fonts

You can see that the serif font has additional small details at the ends of vertical and horizontal strokes of each character. The sans serif font lacks these details. For most Western European characters these extra details on the serif fonts are non-significant stylistic features that don't change the identity of the character. Unfortunately, some of Microsoft's earlier attempts at Unicode fonts left off details that are essential to the identity of certain phonetic characters. For example, the vowel in the word "hit" when transcribed phonetically and displayed using certain older MS unicode fonts chopped off the phonetically essential top and bottom horizontal lines (which had presumably been thought to be mere serifs by the font designers). They have fixed these problems in very recent fonts but the fonts with these errors are still widespread. For example, the newer Arial Unicode MS font (supplied with Office 2007) doesn't have the problem but Arial (the version supplied with Vista) still has this problem. In the following image the left hand (incorrect) transcription was done with Arial (the version supplied with Windows Vista) and the right hand (correct) transcription was done with Arial Unicode MS (version supplied with MS Office 2007). Note, however, that the much older MS font, Lucida Sans Unicode didn't make this error.

Using Serif and Sans Serif to Test the Phonetic Font

The web pages on this site have been set up so that when phonetic text is encountered the system looks for fonts in the following order:-

  1. Charis SIL
  2. Doulos SIL
  3. Lucida Grande (Macintosh font)
  4. Lucida Sans Unicode (Windows font)
  5. Arial (widespread cross platform font)
  6. Helvetica (widespread cross platform font)
  7. sans-serif (generic font face family)

The first two (1-2) are serif fonts. All of the others (3-7) are sans serif fonts.

Your web browser will look for each in turn and will use the first one it finds. If it finds a font, but not a particular required character, then it should look for that character in the fonts lower on the list. This would result in a sans serif character in the midst of serif characters. Care has been taken to ensure that the characters used in this page are found in all of the first four fonts. Unless you have a Linux system or a very old Mac or Windows machine you should at least have one of 3 or 4 by default.

So, if you do have Charis SIL (or Doulos SIL) installed you will see serif characters in phonetic transcriptions on this site. If you don't have Charis SIL (or Doulos SIL) installed you will see the phonetic transcriptions as sans serif characters.

I Know Charis SIL is Installed but I Still Can't See It! (or it Looks Wrong)

Firstly, make sure you aren't using Internet Explorer (version 7 or earlier). This browser doesn't display some phonetic characters properly no matter how you set up IE (version 7 or earlier). The fonts are displayed correctly by Internet Exploer (version 8 or later).

If you are using one of the preferred browsers, you have just installed the font, but it doesn't look right (or doesn't seem to be installed), then you are probably viewing a cached version of the page (a saved copy of the version you looked at previously). Refresh the page and the phonetic characters should appear. If that doesn't work then restart your browser. If that doesn't work then try re-booting your machine. If all else fails try clearing your browser's cache. On Firefox you can choose to clear only your "Cache" (by unchecking the other tick boxes), whilst on Internet Explorer you can choose to only delete "Temporary Internet Files". The procedure should be similar for Safari. If these steps don't work then check your font folder and see if the font is actually in that folder (if it isn't then it hasn't been installed). If you don't know how to do these tasks, ask a friend who does (only ask me as a last resort).
