### Better Components Generation in Glyphs ###

By adding the following glyphs, you will enable auto-generation of many components for the GF Latin encodings.

```
DZ
Dz
dz
slashlongcomb
slashshortcomb

```

### Armenian Dram ###

Armenian Dram currency symbol is a recommended addition to any Cyrillic-supporting fonts, due to popular use of Russian in Armenia.

	0x058F  ֏ dram-arm


### Better Vietnamese ###

Stacked Vietnamese accents may require custom tailoring. This can be achieved by adding additional accents. Glyphs will automatically place these newly created accents were applicable.

### Polish Kreska ###

Polish Kreska shares the same unicode as the acute accent, however it is designed differently. Explore Adam Twardoch's guidelines on [Polish Kreska](2)

Here is a list of additional glyphs for better Polish support:

```
Cacute.loclPLK Nacute.loclPLK Oacute.loclPLK Sacute.loclPLK Zacute.loclPLK cacute.loclPLK nacute.loclPLK oacute.loclPLK sacute.loclPLK zacute.loclPLK acutecomb.loclPLK acutecomb.loclPLK.case
```

### STRASSE or Straße? ###

The Google Lating Plus encoding includes **ẞ Germandbls U+1E9E**. 

Does your font include Small Capitals?
For better compatibility you may consider adding the germandbls.calt glyph to access ẞ U+1E9E in Small Caps fonts. In Glyphs go to *Glyph > Add Glyphs*, and paste this code:

```
Germandbls=germandbls.calt
```
	
Add this calt feature:

```
sub @Uppercase germandbls' @Uppercase by germandbls.calt;
sub @Uppercase @Uppercase germandbls' by germandbls.calt;
```

### Duodecimal(dozenal) notation

Add these glyphs for single-digit representations of numbers 10 and 11.

```
U+218A (turned digit two) 
U+218B (turned digit three)
```

N.B. The question of German Uppercase Capital Sharp S is still highly debatable, and its usage hasn't passed into the official orthography. 
### Cyrillic component building

These glyphs are used for component building and are non-exportable. Don't forget to set the non-export tag.

```
descender-cy
descender-cy.case
verticalbar-cy
verticalbar-cy.case
```
